==Bugfix log for 0.27.169.33a:==
+
Dwarf Fortress is a constant work in progress, and is thus full of '''bugs'''. Some of them are minor and completely harmless, some are small and annoying, and some are major and even game-changing. This page is a historical list of some of the best-known bugs in 40d; an official compilation of all bugs, and their development status, can be found on the [http://www.bay12games.com/dwarves/mantisbt/my_view_page.php Mantis Bug Tracker]. Please do '''not''' report new bugs for this version; if the problem still exists in the current development version it should be reported on the [http://www.bay12games.com/dwarves/mantisbt/my_view_page.php bug tracker] for that version instead. If you have issues signing up for the bug tracker, see the [http://www.bay12forums.com/smf/index.php?board=6.0 forum bug tracker board] for instructions (but don't report bugs on the forum either).

==Miners Stuck==
+
=== "Large [blank]" ===
(needs testing in latest version)
 
My Miners, after they mind a floor down and then started mining to the left, stopped and tried to move the boulders that were left behind but when they did they couldn't find their way. What I did was I mined to the right a little then I made two ramps right next to each other, on the lower level, and then I mined to the left. Some stone was present and so my miners tried to move it to the stock pile but they couldn't find the way back to the surface. They were stuck in an infinite loop of not finding there path.
 
  
== Floating Dwarves and etc ==
+
I was minding my own business, trading with some nice human merchants... when all of a sudden I find a very very strange item.
(needs testing in latest version)
 
Certain situations can occur that will break pathfinding on a dwarf and leave him stranded in the air.  Building a stairs to his location doesn't seem to help.
 
  
== Floating Boulders ==
+
It costs 40# and has a weight of 6r. The weirdest thing is both its name and description;
(needs testing in latest version)
+
Name: <-large ->
If you dig an up ramp to a tile with boulders, then remove the up ramp, the boulders may end up floating in midair.
+
Description: This is a well-crafted large .
:If you get this you can build a floor underneath the boulder (on the higher level of course) and it fixes the problem.
 
  
== Rewalling Quirks ==
+
As you can see, the game tried to create a large something... but whatever it was didn't exist. Just thought you might like to know. [[User:AlexFili|AlexFili]] 10:30, 7 May 2008 (EDT)
 +
:This... is already known and floats around the known bugs list on the dev pages. --[[User:GreyMario|GreyMario]] 14:06, 7 May 2008 (EDT)
  
# Diagonal rewalling is silently pathblocked.
+
Oh alright. Just making sure it isn't just me. By the way, the item in question is a gem. Hope that helps. [[User:AlexFili|AlexFili]] 08:09, 8 May 2008 (EDT)
# Rewalling from the top of a ramp is apparently silently pathblocked.
 
# Walls made by rewalling start out smoothed, but cannot be engraved.
 
  
== Optimal pathfinding ==
+
My Dungeon Master is demanding "item in Throne Room/Office", a similar sort of bug perhaps? I have no idea what sort of item he wants, but man, does he ever want it. [[User:Bryan Derksen|Bryan Derksen]] 19:34, 14 June 2008 (EDT)
  
When digging an area from two ends (ie. farm from outside river and inside hallway) dwarves sometimes choose to start digging from the other end, causing them to run back and forth, digging just one rock at a time in worst case.
+
=== Merchant in Adventure Mode ===
  
It is also common for digging/item placement to start with the tile to the right of the dwarf, even if the path is closer using another direction. Keep this in mind when placing floodgates or digging out areas where you could paint yourself in a corner.
+
(This conversation pretty much sums up the whole issue).
 +
:Flauncy, Swordsman: Let's trade.
 +
:Mispi Emanraji, Merchant: You should probably try a merchant.
 +
>_< --[[User:AlexFili|AlexFili]] 10:05, 16 June 2008 (EDT)
  
== The Most Dangerous Game ==
+
:Was the aforementioned merchant in his shop? Was he about to leave or did he just enter? If so, "Merchants don't act like merchants unless in their shop." --[[User:Savok|Savok]] 12:47, 16 June 2008 (EDT)
  
If you have two or more miners digging a channel, they ''will'' try to dig it under each other's feet, sending their fellows plummeting into the hole. (If you only designate channels on un-mined squares, this won't happen, as the dwarves seem to mine both levels' tiles out at the same time)
+
::Was it an Elf Merchant? As far as I can tell, only shopkeepers trade, and only in their shops; and elf merchants don't have shops, so. I imagine (though I haven't observed it) that a human merchant who wasn't a shopkeeper would have the same issue. My advice: Grab merchant by throat with right upper arm. Choke merchant by throat with right upper arm. Strangle merchant by throat with right upper arm. Repeat last step as necessary. Problem solved! --[[User:Zombiejustice|Zombiejustice]] 13:51, 16 June 2008 (EDT)
  
Even a single miner digging a channel can get into trouble. Miners may "paint themselves into a corner" and end up surrounded by channel tiles, unable to remove the last channel tile under their own feet.
+
::: I should probably mention, the merchant in question was in the Mayor's house with all the drunks. Still, I would have expected him to say "Oh, I'm not in my merchants house, sorry." or something similar not "You should probably try a merchant". --[[User:AlexFili|AlexFili]] 06:59, 17 June 2008 (EDT)
  
Related but not really: If you ask a dwarf to remove a floor you've built, he will -stand on it- while removing it. Problematic if, say, it's over a hundred-yard cliff, but still a good way to get the sand down covering the floor at the magma forge 6 levels down.
+
=== Legendary Wagon (I'm serious) ===
 +
In legends mode, I've got about 10 entries that are strange. I will quote one of them;
  
== We All Fall Down==
+
::::: , ""
 +
was a wagon born in 883.
 +
In the early autumn of 1058, was scuttled in Flowervoiced.
  
If a dwarf goes to remove a floor, he removes it while standing on it, and will subsequently fall down if there's no ground underneath. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)
+
Any idea what this means? --[[User:AlexFili|AlexFili]] 10:01, 16 June 2008 (EDT)
  
: This also occurs when removing staircases. --[[User:JT|JT]] 20:26, 31 October 2007 (EDT)
+
It means that wagons are actually living, breathing entities! I discovered something similar when i accidentally 'killed' a pair of human caravan wagons in fortress mode. they appproached my fortress through an area where a wall was being built, and as they were passing the square that was directly above my underground trade depot (don't know if that was coincidence or played into the bug) they both somehow got stuck in the semi constructed wall. then after a few months they vanished... leaving all their stuff on the ground for my dwarves to loot. the guards and merchants wandered off, and they showed up on the list of units as dead wagons. as this was only my second fortress playing with version 39e, I was extremely confused at the time. --[[User:FruityBix|FruityBix]] 19:52, 31 August 2008 (EDT)
  
== Weight Issues ==
+
=== Teleporting Goblin Items ===
Are steel bolts supposed to weigh 10 units each? It makes a quiver of 25 three times as heavy as the crossbow [[User:HeckRuler|HeckRuler]] 17:09, 1 November 2007 (EDT)
+
When you drop a goblin cage into magma, their charred, burning clothes and red-hot weapons magically appear at the trap location they were caught in.  Be sure you didn't catch them <em>inside</em> before you dump!  Toady already knows about this one, but it's not yet listed as solved on the official page.  --[[User:Corona688|Corona688]] 13:08, 2 November 2008 (EST)
  
== Startup - Civilization Selection ==
+
=== Pitting Creatures ===
When you are choosing you starting location, if you move the starting zone on the local (leftmost) map, cycle to the Civ Selection tab (rightmost), and change Civ, the area selected on the left will default to original location and size.
 
  
[[User:Rylen|Rylen]]  23:21, 1 November 2007 (EDT)
+
Once you capture a hostile creature in a Cage Trap and place the cage in a stockpile / somewhere away from the capture point, and select a zone for the creature to be pitted, your dwarves will take the creature out, cancel all tasks and run away from it, Leaving the creature to escape. Weird glitch / bug. Only way to bypass it is to build a cage, press X to expand the list and select the creature cage I.E. Kobold Cage (Pine), link the cage up to a lever to release it - Good for a massive prisoner war. Or, to leave the cage as it is after the trap has sprung.
  
== Theft in Adventure Mode ==
+
== Issues ==
In the 2D version, you had to actually reach the edge of the map to lay permanent claim to your five-fingered discounts, which was fine.  In the 3D version, the area maps are seamless, but the game still seems to think you have to touch a seam before you can own your five-fingered discounts, which very obviously causes problems for would-be thieves and other sorts who would just like to enjoy their newfound treasures in peace.  Note that it is *not* a bug that you have to walk over to things you purchase in shops and pick them up yourself, despite the behavior being different in just about every other game out there (for those who know not what I mean, other games magically transport that new sword right into your backpack after your purchase, and sometimes even right into your hands). --[[User:BDR|BDR]] 08:41, 2 November 2007 (EDT)
 
  
== Love Conquers All ==
+
=== Trader Problem ===
  
A chained animal, when they spot their original trainer, will break free of their chains and go to greet him/her. Hence chaining animals is practically useless.
+
I just had a group of traders spend so long "unloading" that they left before I could do any trading. This is only the second time the dwarven trade wagon has been here and I really need an anvil...
  
== Outpost liason ==
+
Update... I've tested (five times each to make certain):
The npc dwarf that arrives the first autumn never leaves for me. He eventually gets hungry and goes rampage. Although the [[expedition leader]] has no other tasks, he seems to not be able to fully complete the meeting with the liason. I discussed this in the irc channel and it seems to be some wierd bug.
 
  
''The liason is following the expedition leader around trying to talk to him. Atleast in my game, whenever the exp.leader has a idle moment, part of the meeting takes place until he has idled enough times to finish the meeting completely. (edit by: Uberubert)''
+
-- One merchant and three wagons with five depots that were operational and accessible BEFORE the wagons arrived.  
  
''Apparently it sometimes happens even if the liason finishes the meeting. Best answer I've seen is that the liason forgets how to use stairs after the meeting, so maybe try to keep your noble's office or other meeting place on the "ground floor." (edit by: Rabid Llama)''
+
'''Result''': Merchant heads to Depot #1, all 3 wagons head to Depot #2, and one of them stops one square short of arrival into the depot. Merchants are "unloading" the whole season and leave before letting me trade. Year 3. (human)
  
''I had a meeting place outdoors and this still happened. It doesn't matter where the meeting takes place. Assuming you can get the meeting to actually occur - which takes some work - if it doesn't properly conclude, the liason will be stuck. (edit by: Captain Failmore)''
+
-- No merchant, two wagons, one depot op/acc as normal.  
  
''Oh, also, for the meeting to even take place or properly conclude, your broker has to have ALL OTHER LABOR turned off. Leave their labors off until the meeting concludes in full. (That is, you've been 'shown the documents' twice and the liaison wishes you well before leaving.) If you let the meeting conclude in full without assigning labor to your broker (who may and probably will wander about aimlessly for some time while the meeting is taking place for reasons I don't know) the liaison WILL leave.
+
'''Result''': Both wagons successfully enter depot. Year 2. (human)
  
==A Time To Wait==
+
-- No merchant, three wagons, one depot op/acc as normal.  
Sieges completely do not work, and goblins will just mill around aimlessly at the edge of the map waiting for your dwarves to come and kill them.  Toady has said something about the AI for sieges being broken.
 
  
==Sticky Keys==
+
'''Result''': All wagons successfully enter depot. Year 5. (human)
Sometimes when you are scrolling on the map the keys will seem to stick, and you will keep scrolling forever. This happens when you release a key out of the order in which it was pressed.
 
  
Example:  
+
:I just had the same issue with elves.  About a month later I get the message, 'one-humped camel has gone stark raving mad!'  ...What?  I don't even HAVE a camel.  I find it trapped and alone at the far lower-right corner of the map and under siege by batmen, carrying all sorts of elven goods.  So maybe this happens when a beast of burden that's part of a caravan gets attacked unattended. [[User:Corona688|Corona688]] 23:48, 6 October 2008 (EDT)
*{{key|8}}
 
*{{key|Shift}}+{{key|8}}
 
*{{key|Shift}}
 
*No key pressed.
 
  
After holding the above keys you will continue going up until you press the following or {{key|Alt}}+{{key|Tab}}.
+
=== Magma Flow ===
  
*{{key|Shift}}+{{key|8}}
+
Magma does not naturally have [[pressure]] because it is "chunky": when a magma pipe is tapped at a certain level, it will not flow upwards like a volcano, even if there is a considerable reservoir of magma nearby.  This is not a bug and is very intentional.  However, if magma is pumped, it gains pressure up to the level of the [[screw pump]], and a pump can push magma through a U shaped passage just fine.
*{{key|Shift}}
 
*{{key|8}}
 
  
This will clear out the pressed key flag in the game.
+
=== Perfect Swimming ===
  
:I've found if you merely press the direction key of the scrolling on the numpad this scrolling stopsNo need to fiddle with the shift or in what order the shift key is pressed.--[[User:Mylon|Mylon]] 17:35, 13 November 2007 (EST)
+
"Brook" tiles are treated as floor tiles over top of caverns.  Think of a thin "force-field" built over top of a riverThe force field allows people to walk across, but also allows them to dip their hands into the water below in order to drink. Though silly from a realism standpoint, this is currently the only possible implementation, and is meant to represent very shallow water flowing through and around rocky gravel.
::That won't work if you were using shift to accelerate your move speed. You have to tap the key with shift pressed to clear out the shift+key then press just key to clear it out as well.--[[User:Ikkonoishi|Ikkonoishi]] 21:38, 13 November 2007 (EST)
 
:Switch Numlock off, fixes it for me --[[User:AdaIsDead|AdaIsDead]] 18:59, 16 November 2007 (EST)
 
  
==Thawing stairs==
+
=== Milking Issue ===
I have a brook that freezes in the winter. Awesome. I dug a down-stairs down into it and started diggin about in the ice. When the thaw came, the ice broke up and the flow resumed, but the stairs remained. Unfortunetly, this is on the old version .32a [[User:HeckRuler|HeckRuler]] 17:44, 15 November 2007 (EST)
 
  
==Picky Elves==
+
To milk something it has to be a [[vermin]]ous creature.  The only milkable thing you can carry is a purring maggot.  Larger creatures are not yet milkable because the AI is not yet implemented to bring the creatures to the [[farmer's workshop]].  It would be relatively simple to implement, but is not a priority at this time.
The elves will not trade for Orthoclase or Gabbro rock crafts because the crafts were once alive.
 
  
=Fixed Bugs=
+
Note that while you cannot milk larger animals yourself, civilisations can still milk animals "off screen" for your benefit.
  
== Fatal crash on embark ==
+
=== Building a Wooden Weapon... Rack ===
(partially fixed in 0.27.169.33a)
 
(fully? fixed in 0.27.169.33b)
 
The first fortress I tried to create resulted in the program's hard crash right after the disembarkment screen. I has manually selected the location (sorry I don't remember it's features) and equipment. I swapped out the anvil for a LOT of items: extra barrels, food, crossbows and bolts. I also swapped the copper pick out for a steel pick. The fortress was not created in the files. I think it also refused to save the world map, but that might be user error. The next default fortress worked fine. [[User:HeckRuler|HeckRuler]] 15:27, 1 November 2007 (EDT)
 
  
== Hole in a Wall ==
+
There is a minor problem with the [[carpenter's workshop]].  Inexperienced players might be confused because in the build menu it says "Construct wooden Weapon", but they will get a [[weapon rack]] out of the deal. This isn't a bug, merely a shortcoming of the interface.  You cannot actually build wooden weapons at the carpenter's workshop; the full name, "Construct wooden Weapon rack", is cut off in the default view, and can be seen if {{k|Tab}} is used to expand the menu.  Expanding the menu will reveal that the option does not specify constructing a wooden weapon, but rather a wooden weapon ''rack''.
(explicitly fixed in 0.27.169.33b)
 
If a dwarf removes a floor that's on top of a wall, the dwarf will get stuck, and the Visualisation reveals that the floor tile of that wall is completely missing. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)
 
  
== Multiple Mayors ==
+
=== Split-level River ===
(explicitly fixed in 0.27.169.33b, ability to designate leader was also removed?)
+
I loaded up a section of my world and found a split-level river- that is, a river that for half of the map is on ground-level and half of the map is one z-level up. This may just seem like a cool thing to most of you, but the upper river has now started flooding out and consuming the entire lower river basin- something that I've been informed shouldn't happen.  If someone will give me the address and directions for sending my world / creation log, I can pass it along to the developers for review. --[[User:Lucien|Lucien]] 23:30, 13 June 2008 (EDT)
You can end up with multiple mayors in your fortress: One from the expedition leader, and one elected later when the population gets high enough. These positions should probably be seperate jobs, or the elected one should replace the original mayor/leader, and he/she should become 'mayor emeritus' or something.
 
  
From what I have seen there is only 'one' active Mayor (whoever is on the noble screen as having the job) but the dwarves retain the title when they are removed from office. I have 6 mayors running around but only one (the current one) does the mayor's work. It's confusing as hell --[[User:Gorfob|Gorfob]] 22:35, 8 November 2007 (EST)
+
I also have this issue, however it is really satisfying to watch the carp the killed 4 of my original 7 dwarves spawn outside the river, die and then fall in, the weird thing is, it empties and then about 15 grid squares farther along the river, it is still ful and flowing on its original course. I also have an issue at a river junction where on one z-level there is blood, that looks like it is flowing into a waterfall, one z-level lower, there is no blood, another z-level down, there is still another river without a side wall, yet it is still running.  please, this is on a community fortress, can we get this fixed?
  
== Infinite [[Blood]] ==
+
=== Creatures Don't Always Use Graphics ===
(temporary? fix in 0.27.169.33a by autocleaning all tiles at end of each season)
 
For some reason, blood is constantly 'growing'. Blood from an accident in the centre of the village (wooden buildings) seems to be spreading further and further without dissapearing. --[[User:Plasma|Plasma]] 20:23, 31 October 2007 (EDT)
 
  
:Don't you know?  Your dwarves are building a shrine to Armok. -[[User:EarthquakeDamage|EarthquakeDamage]] 11:10, 2 November 2007 (EDT)
+
When a creature is caught in a cage and put in a stockpile, and graphic sets are used, the creature is displayed with the correct graphic tile.  But should you install the goblin cage anywhere, the graphic is ignored and the traditional letter displayed instead.
 +
this also happens with dead creatures, even dwarves.
  
related:  not that mine's disappearing, but my fortress has a cleaning jobspam related to the blood - "such and such cancels job - can't find path x23490872340982734098273409283", just like empty archer traps in old-school df.  any help?  or do I have to abuse traffic designations (and my main hut) to get rid of the damned stuff?
+
== Official bug list ==
  
::For both problems, try designating a single dwarf to cleaning jobs only. Let me know if that helps, because I had similar problems but the blood was dealt with eventually and cleaned. [[User:Schm0|Schm0]] 11:58, 11 November 2007 (EST)
+
The official list of bugs is available on the Dwarf Fortress [http://www.bay12games.com/dwarves/mantisbt/my_view_page.php bug tracker].
  
Related to the above issue, [[mud]] can be tracked through your fortress by dwarves stepping over it. The tracked mud is treated like fresh mud, and will thus take a very long time to dry. Dwarves stepping over this new mud will then track it elsewhere, causing the mud to eventually take over your fortress. Dwarves stepping onto a [[bridge]] will stop tracking mud around, so it may be possible to stop the spread of mud by building a bridge outside of the muddy area.

==Sew plant fiber image crash==
 
(explicitly fixed in 0.27.169.33b)
 
Ordering plant fiber image in Clothier's Shop reliably crashes the game.
 
:Fixed, according to the dev blog.--[[User:Mylon|Mylon]] 17:36, 13 November 2007 (EST)
 
 
 
==Buff Swimmers==
 
(explicitly fixed in 0.27.169.33b)
 
All creatures get stat boosts by training up skills.  This is normal.  Aquatic creatures can train swimming simply by being on the map.  This leads to some very buff carp or lizardmen or other creatures if they've been in water for a significant amount of time.
 
:According to the dev blog, this has been fixed.
 
 
 
== Ducky Go Down The Hoooole  ==
 
(partially fixed in 0.27.169.33a)
 
(fully? fixed in 0.27.169.33b)
 
Wells crash the game now and then.
 
 
 
I had a crash on my well the moment a dwarf hit it up for water when the stream under had frozen or reduced height, unsure. --arr
 
 
 
==Trading crash==
 
(explicitly fixed in 0.27.169.33b, had to do with seed prices)
 
Sometimes offering a trade to traders the game crashes. Sometimes looking at the inventory of traders using the view units screen crashes the game.
 
 
 
== Contents Under Pressure  ==
 
(explicitly fixed in 0.27.169.33a)
 
Melting metal items produces a crapload of metal.
 
 
 
Assumed to be a code error involving the repacement of a / with a * (i.e. multiplying by 30 instead of dividing, in the case of metal bolts).
 
 
 
== Making Metal Bars ==
 
(explicitly fixed in 0.27.169.33a)
 
At [[Talk:Galena]] a bug is mentioned that apparently gives you less metal bars than you should have when producing them at a smelter. I havent confirmed it though. --[[User:Mizipzor|Mizipzor]] 17:35, 31 October 2007 (EDT)
 
 
 
:This refers to alloys.  When making an alloy, only one bar is created, instead of the 2-4 that are supposed to show up.  Avoid alloys until the version after 0.27.169.32a is released.--[[User:McFrugal|McFrugal]] 20:08, 31 October 2007 (EDT)
 
 
 
=Bugs that aren't REALLY bugs=
 
 
 
==Too tired to sleep==
 
If a wounded dwarf continually falls unconscious due to their wounds, it will disrupt their sleep, so they eventually go mad of sleep deprivation.
 
 
 
== Magma Flow ==
 
Magma will not flow UP stairs. It will flow DOWN them just fine.
 
Update: Toady mentioned this has to do with magma using the 'chunky' fluid flow, which does not respect pressure.
 
 
 
== Perfect Swimming ==
 
"Brook" tiles are treated as floor instead of the open space they're supposed to be.  Dwarves, animals, even--that's right--wagons can travel over rivers.
 
(was this fixed on 0.27.169.33a?)
 
:This isn't a bug.  There's just no good way to represent a shallow river with the current depth system.  Think of the water tiles below the brook as being an aquifer of sorts.  Solid ground, but containing water.--[[User:McFrugal|McFrugal]] 01:37, 2 November 2007 (EDT)

This article is about an older version of DF.

Dwarf Fortress is a constant work in progress, and is thus full of bugs. Some of them are minor and completely harmless, some are small and annoying, and some are major and even game-changing. This page is a historical list of some of the best-known bugs in 40d; an official compilation of all bugs, and their development status, can be found on the Mantis Bug Tracker. Please do not report new bugs for this version; if the problem still exists in the current development version it should be reported on the bug tracker for that version instead. If you have issues signing up for the bug tracker, see the forum bug tracker board for instructions (but don't report bugs on the forum either).


"Large [blank]"[edit]

I was minding my own business, trading with some nice human merchants... when all of a sudden I find a very very strange item.

It costs 40# and has a weight of 6r. The weirdest thing is both its name and description; Name: <-large -> Description: This is a well-crafted large .

As you can see, the game tried to create a large something... but whatever it was didn't exist. Just thought you might like to know. AlexFili 10:30, 7 May 2008 (EDT)

This... is already known and floats around the known bugs list on the dev pages. --GreyMario 14:06, 7 May 2008 (EDT)

Oh alright. Just making sure it isn't just me. By the way, the item in question is a gem. Hope that helps. AlexFili 08:09, 8 May 2008 (EDT)

My Dungeon Master is demanding "item in Throne Room/Office", a similar sort of bug perhaps? I have no idea what sort of item he wants, but man, does he ever want it. Bryan Derksen 19:34, 14 June 2008 (EDT)

Merchant in Adventure Mode[edit]

(This conversation pretty much sums up the whole issue).

Flauncy, Swordsman: Let's trade.
Mispi Emanraji, Merchant: You should probably try a merchant.

>_< --AlexFili 10:05, 16 June 2008 (EDT)

Was the aforementioned merchant in his shop? Was he about to leave or did he just enter? If so, "Merchants don't act like merchants unless in their shop." --Savok 12:47, 16 June 2008 (EDT)
Was it an Elf Merchant? As far as I can tell, only shopkeepers trade, and only in their shops; and elf merchants don't have shops, so. I imagine (though I haven't observed it) that a human merchant who wasn't a shopkeeper would have the same issue. My advice: Grab merchant by throat with right upper arm. Choke merchant by throat with right upper arm. Strangle merchant by throat with right upper arm. Repeat last step as necessary. Problem solved! --Zombiejustice 13:51, 16 June 2008 (EDT)
I should probably mention, the merchant in question was in the Mayor's house with all the drunks. Still, I would have expected him to say "Oh, I'm not in my merchants house, sorry." or something similar not "You should probably try a merchant". --AlexFili 06:59, 17 June 2008 (EDT)

Legendary Wagon (I'm serious)[edit]

In legends mode, I've got about 10 entries that are strange. I will quote one of them;

, ""

was a wagon born in 883. In the early autumn of 1058, was scuttled in Flowervoiced.

Any idea what this means? --AlexFili 10:01, 16 June 2008 (EDT)

It means that wagons are actually living, breathing entities! I discovered something similar when i accidentally 'killed' a pair of human caravan wagons in fortress mode. they appproached my fortress through an area where a wall was being built, and as they were passing the square that was directly above my underground trade depot (don't know if that was coincidence or played into the bug) they both somehow got stuck in the semi constructed wall. then after a few months they vanished... leaving all their stuff on the ground for my dwarves to loot. the guards and merchants wandered off, and they showed up on the list of units as dead wagons. as this was only my second fortress playing with version 39e, I was extremely confused at the time. --FruityBix 19:52, 31 August 2008 (EDT)

Teleporting Goblin Items[edit]

When you drop a goblin cage into magma, their charred, burning clothes and red-hot weapons magically appear at the trap location they were caught in. Be sure you didn't catch them inside before you dump! Toady already knows about this one, but it's not yet listed as solved on the official page. --Corona688 13:08, 2 November 2008 (EST)

Pitting Creatures[edit]

Once you capture a hostile creature in a Cage Trap and place the cage in a stockpile / somewhere away from the capture point, and select a zone for the creature to be pitted, your dwarves will take the creature out, cancel all tasks and run away from it, Leaving the creature to escape. Weird glitch / bug. Only way to bypass it is to build a cage, press X to expand the list and select the creature cage I.E. Kobold Cage (Pine), link the cage up to a lever to release it - Good for a massive prisoner war. Or, to leave the cage as it is after the trap has sprung.

Issues[edit]

Trader Problem[edit]

I just had a group of traders spend so long "unloading" that they left before I could do any trading. This is only the second time the dwarven trade wagon has been here and I really need an anvil...

Update... I've tested (five times each to make certain):

-- One merchant and three wagons with five depots that were operational and accessible BEFORE the wagons arrived.

Result: Merchant heads to Depot #1, all 3 wagons head to Depot #2, and one of them stops one square short of arrival into the depot. Merchants are "unloading" the whole season and leave before letting me trade. Year 3. (human)

-- No merchant, two wagons, one depot op/acc as normal.

Result: Both wagons successfully enter depot. Year 2. (human)

-- No merchant, three wagons, one depot op/acc as normal.

Result: All wagons successfully enter depot. Year 5. (human)

I just had the same issue with elves. About a month later I get the message, 'one-humped camel has gone stark raving mad!' ...What? I don't even HAVE a camel. I find it trapped and alone at the far lower-right corner of the map and under siege by batmen, carrying all sorts of elven goods. So maybe this happens when a beast of burden that's part of a caravan gets attacked unattended. Corona688 23:48, 6 October 2008 (EDT)

Magma Flow[edit]

Magma does not naturally have pressure because it is "chunky": when a magma pipe is tapped at a certain level, it will not flow upwards like a volcano, even if there is a considerable reservoir of magma nearby. This is not a bug and is very intentional. However, if magma is pumped, it gains pressure up to the level of the screw pump, and a pump can push magma through a U shaped passage just fine.

Perfect Swimming[edit]

"Brook" tiles are treated as floor tiles over top of caverns. Think of a thin "force-field" built over top of a river. The force field allows people to walk across, but also allows them to dip their hands into the water below in order to drink. Though silly from a realism standpoint, this is currently the only possible implementation, and is meant to represent very shallow water flowing through and around rocky gravel.

Milking Issue[edit]

To milk something it has to be a verminous creature. The only milkable thing you can carry is a purring maggot. Larger creatures are not yet milkable because the AI is not yet implemented to bring the creatures to the farmer's workshop. It would be relatively simple to implement, but is not a priority at this time.

Note that while you cannot milk larger animals yourself, civilisations can still milk animals "off screen" for your benefit.

Building a Wooden Weapon... Rack[edit]

There is a minor problem with the carpenter's workshop. Inexperienced players might be confused because in the build menu it says "Construct wooden Weapon", but they will get a weapon rack out of the deal. This isn't a bug, merely a shortcoming of the interface. You cannot actually build wooden weapons at the carpenter's workshop; the full name, "Construct wooden Weapon rack", is cut off in the default view, and can be seen if Tab is used to expand the menu. Expanding the menu will reveal that the option does not specify constructing a wooden weapon, but rather a wooden weapon rack.

Split-level River[edit]

I loaded up a section of my world and found a split-level river- that is, a river that for half of the map is on ground-level and half of the map is one z-level up. This may just seem like a cool thing to most of you, but the upper river has now started flooding out and consuming the entire lower river basin- something that I've been informed shouldn't happen. If someone will give me the address and directions for sending my world / creation log, I can pass it along to the developers for review. --Lucien 23:30, 13 June 2008 (EDT)

I also have this issue, however it is really satisfying to watch the carp the killed 4 of my original 7 dwarves spawn outside the river, die and then fall in, the weird thing is, it empties and then about 15 grid squares farther along the river, it is still ful and flowing on its original course. I also have an issue at a river junction where on one z-level there is blood, that looks like it is flowing into a waterfall, one z-level lower, there is no blood, another z-level down, there is still another river without a side wall, yet it is still running. please, this is on a community fortress, can we get this fixed?

Creatures Don't Always Use Graphics[edit]

When a creature is caught in a cage and put in a stockpile, and graphic sets are used, the creature is displayed with the correct graphic tile. But should you install the goblin cage anywhere, the graphic is ignored and the traditional letter displayed instead. this also happens with dead creatures, even dwarves.

Official bug list[edit]

The official list of bugs is available on the Dwarf Fortress bug tracker.
