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. Some of the best-known bugs are compiled below; 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 bug tracker] and an informal [http://www.bay12forums.com/smf/index.php?topic=111051.0 poll of the worst bugs] is available in the forums. Please do '''not''' report bugs here; they should be sent to the [http://www.bay12games.com/dwarves/mantisbt/my_view_page.php Mantis BT] 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).

Some bugs {{dffd|6741|were fixed in v0.34}} by a temporary binary patch made by Quietust and other users; most of these fixes were rolled into v0.40.

== Severe bugs ==
These bugs can significantly interfere with play.

* {{bugl|10369}}: Crash (likely) when Dwarves return from mission (without squad leader?)
* {{bugl|10340}}: Visitors arrive very early, ignore visitor cap, and act strangely -- fixed v0.44.03
* {{bugl|10335}}: "an unknown creature is slain" - incident/reputation/identity bugged -- fixed v0.44.03
* {{bugl|9888}}: Crash when a weapon in a trap is destroyed by wear -- fixed v0.44.01
* {{bugl|10028}}: Crash when a ballista arrow is destroyed by wear -- fixed v0.44.01
* {{bugl|9954}}: Crash when filtering material type condition in work order
* {{bugl|9653}}: Tavern keeper/performers repeatedly serve alcohol until patrons drink themselves to death
**Workaround: do not assign tavern keepers or performers
* {{bugl|9438}}: Caravans/invasions do not come reliably from accessible civilizations
* {{bugl|9593}}: Caravans/invasions sometimes get "stuck" off-map
**Workaround: teleport merchants on to map with dfhack
**Workaround: save prior to arrival, and reload until the caravan successfully appears
* {{bugl|9496}}: Tiny undead creatures immune to pulping, ridiculously difficult to kill -- fixed v0.44.01
**Workaround: cage trap, or destroy with dfhack
* {{bugl|9440}}: Wounded dwarves die of dehydration if they grab a goblet they can't use
**Workaround: forbid all goblets so dwarves will drink straight from the barrels
* {{bugl|7161}}: Morale is screwy -- saves demonstrating morale problems in v0.44.03+ requested 
** Partially fixed in 0.40.10. Bugfixes for morale are ongoing.
** Workaround: mod creatures to have natural Discipline skill
** Workaround: barracks training raises Discipline
** Workaround: continual exposure to sentient corpses raises Discipline (along with feelings of horror)
* {{bugl|7185}}: Scared traders immediately scuttle wagons and leave. 
* {{bugl|6586}}: Dwarves climb trees for no obvious reason, get stuck, and die/fall -- fixed v0.44.01
* {{bugl|9004}}: Items in containers are "unavailable" while a dwarf is hauling another item to store in the container
** Workaround: new STORE_DIST_* settings in [[d_init.txt]] can tweak the behavior.
** Workaround: clever [[Stockpile Design]]s can reduce the impact
** Workaround: avoid using containers (use [[exploit|quantum stockpiles]], [[minecart]] stockpiles, or no stockpiles instead)
* {{bugl|7107}} Fighting berserk citizens and citizen werebeasts causes defenders to lose loyalty.


== New bugs ==
These bugs are new in recent versions (v0.42+).  (There are many more; these are just a few of the most prominent.)

* {{bugl|10346}}: NPCs demanding other characters identify themselves in a loop
* {{bugl|10341}}: Canceling a mission after some dwarves have left the map prevents them from returning[https://youtu.be/-PdqgmZQEbU?t=32812] -- fixed v0.44.03
* {{bugl|10349}}: Were-dwarfs stuck in weird spot between injured and healed
* {{bugl|10353}}: Ending the display of an item leads to cancellation spam and very low priority transfer to stockpile and to next display place -- fixed v0.44.03
* {{bugl|9787}}: Scribes intermittently stop copying works in the library
**Workaround: forbid then unforbid all [[quire]]s
* {{bugl|9221}}: Visiting scholars leave carrying fortress books/scrolls/copies/codices
* {{bugl|9567}}: Animals get distracted over time by "unmet needs"


== Lingering bugs ==
These bugs are not new to v0.42/v0.44, but have been confirmed as still existing.

* {{bugl|1451}}: Military equipment interferes with civilian equipment (picks/axes/crossbows/quivers). It is not possible to use a single axe for both [[wood cutter|wood cutting]] and combat, or a single pick for both [[miner|mining]] and combat. Crossbows in the hands of [[hunter]]s can also cause problems.
* {{bugl|4552}}: Siegers waiting by bodies of dead leaders. (fixed?)
* {{bugl|94}}: Seriously wounded dwarfs sometimes don't get taken to bed.
* {{bugl|2712}}: Weapons, especially whips, cut through steel armor like butter.
**Workaround: appropriate [[modding]] to [http://www.bay12forums.com/smf/index.php?topic=115448 nerf] these weapons
* {{bugl|2780}}: Pond/pool populations (e.g. pond turtles) do not replenish, gradually become [[extinct]]
** Supposedly fixed in 0.40.01 but reported to still be happening with ponds
* {{bugl|535}}: Equipping weapons/armor on military is erratic. This is a long-standing bug that has been slowly but surely rolled back.
* {{bugl|296}}: Pools/smears/spatters of blood, dust and other materials multiply themselves, get tracked around too much. [[Contaminant]] physics are strange in Dwarf Fortress; instead of washing away, when exposed to running water, it will actually multiply to other tiles.
**Workaround: routinely run [https://github.com/DFHack/dfhack/blob/master/Readme.rst#clean clean] in [[Utility:DFHack|DFHack]]
* {{bugl|4550}}: Dodging into river/lava/pit etc. Apparently, dwarves are stupid. Related: they tend to get thrown off of [[waterfall]]s and die from fall damage because they did not account for the current.
* {{bugl|425}}: Dwarves perform [[cleaning]] erratically at best.
**Workaround: routinely run [https://github.com/DFHack/dfhack/blob/master/Readme.rst#clean clean] in [[Utility:DFHack|DFHack]]
* {{bugl|5986}}: Designating large areas for smoothing slows game to a crawl.
* {{bugl|136}}: When embarking on large area, DF hits 2GB memory limit and crashes (Windows only).
**Fix: 64-bit version of release v0.43.05 removes the 2GB limit
**Workaround: [http://www.ntcore.com/4gb_patch.php NTCore's 4GB fix], which will not only increase the memory limit, but will improve performance overall.
* {{bugl|797}}: Animals repeatedly path through "tightly closed" [[door]]s causing lag.
* {{bugl|4065}}: Untradeable creatures (hostiles, wild animals) are released from [[cage]]s when the cages are ordered taken to the [[trade depot]].
* {{bugl|1582}}: Injured dwarf in bed in stocked hospital ignored by idle doctors. Medical jobs are too low-priority, and will be ignored in favor of pretty much everything else, hauling included, forcing players that need to administer medical care to disable all other labors; and even then, doctors tend to idle a bit in between their jobs.
* {{bugl|5097}}: Names overwriting text with TrueType and {{bugl|5696}} strange gaps in report texts.  
**Workaround: Hitting F12 to toggle True Type can often get you around this problem.
* {{bugl|2587}}: Saving fails silently when folder is not writeable (due to full disk, permissions, etc) 
* {{bugl|8383}}: Flying/swimming/climbing creatures can move vertically-diagonal through walls with down-stairways/twigs above
* {{bugl|8426}}: Foreign nobles elevated along with fortress nobles, make regular mandates and demands
* {{bugl|8698}}: Dwarf entering a strange mood when isolated (e.g. on a stepladder) causes severe lag
* {{bugl|7274}}: Dwarves occasionally attempt to perform jobs at a distance, with predictably poor results
** Related to {{bugl|7825}} marked as fixed in 0.40.07 -- #7274 needs verification.
* {{bugl|7444}}: Sparring dwarves can knock each other through walls with charge attacks.
* {{bugl|7872}}: Trees grow through bridges, can make the bridge unusable.
* {{bugl|7760}}: Dwarves construct walls from wrong side, wall themselves out of fortress or into alcove
* {{bugl|7447}}: Problems reported [[brewing]].
** {{bugl|7423}}: Embark-purchased fruit must be removed from bags for use.
** {{bugl|9004}}: Items in a container are "unavailable" while a dwarf is hauling another item to store in that container.
** Corrupted raws will remove brewing options from the still (often occurs when installing outdated mods, including tile sets)

-When reporting a bug:
+Some bugs {{dffd|6741|were fixed in v0.34}} by a temporary binary patch made by Quietust and other users; most of these fixes were rolled into v0.40.
-* Make a note of any mods you're using.  If you made the mod yourself, include the raws for any relevant objects.
-* If the game is crashing or refusing to open, include any error message that appears, along with your computer specifications and operating system.
-* If you have a save that reliably reproduces the bug, it may be helpful to upload the save to the [https://dffd.bay12games.com/category.php?id=20 DF File Depot - Bugged Saves] or another file hosting site.
-== Major bugs with workarounds ==
+== Severe bugs ==
-{{catbox|Bugs}} This is a list of major bugs with workarounds that would be useful for most players to know. Bugs added to this list should: 1) impact most players in a significant way in the current version, and 2) have some workaround that is useful to share. Please link the source of any posted workarounds.
+These bugs can significantly interfere with play.
-* {{bugl|0012008}}: Dwarves will not equip [[Ammunition|ammunition]]. When a squad is created, it takes note of the amount of ammunition in the fortress but never updates this figure.
+* {{bugl|10369}}: Crash (likely) when Dwarves return from mission (without squad leader?)
-**Workaround: Set up a [[Squad#Equipping_soldiers|uniform]] which includes a ranged weapon. Form a new squad using this uniform, which updates the squad's knowledge of how much ammunition is available. Assign the desired dwarves to that squad. Set them to train with a schedule of your choice. The dwarves should equip ammunition. (Note: [[Ambusher|Hunter]] dwarves "reserve" roughly 100 to 200 bolts each. Your ammo stockpile must include more bolts than 200 x number of hunters. This extra ammo will be used by your marksdwarves.) ([https://www.reddit.com/r/dwarffortress/comments/10mwqtw/dwarves_not_equipping_boltsarrows_learn_from_my/ Source])
+* {{bugl|10340}}: Visitors arrive very early, ignore visitor cap, and act strangely -- fixed v0.44.03
-* {{bugl|11985}} ('''Healthcare labors bug''')<span id="healthcare-labors-bug"/>: Dwarves assigned to doctoring occupations not performing doctor labors.
+* {{bugl|10335}}: "an unknown creature is slain" - incident/reputation/identity bugged -- fixed v0.44.03
-**Workaround: Make any change on the work details page, such as adding and removing a dwarf from a work detail. This will cause labors to be properly updated based on occupations. ([https://www.youtube.com/watch?v=79J3X8ulER0&t=1765s source])
+* {{bugl|9888}}: Crash when a weapon in a trap is destroyed by wear -- fixed v0.44.01
-* {{bugl|349}}: [[Animal care]] labor does nothing.
+* {{bugl|10028}}: Crash when a ballista arrow is destroyed by wear -- fixed v0.44.01
-**Workaround: Use DFHack's [https://docs.dfhack.org/en/0.47.04-r2/docs/Plugins.html#dwarfvet dwarfvet plugin]].
+* {{bugl|9954}}: Crash when filtering material type condition in work order
-* {{bugl|1451}}: The equipment required for [[miner]]s, [[hunter]]s, and [[woodcutter]]s to do their job conflicts with military uniforms.
-**Workaround: never assign these three labors to military dwarves.
 * {{bugl|9653}}: Tavern keeper/performers repeatedly serve alcohol until patrons drink themselves to death
-**Workaround: do not assign tavern keepers or performers, or do not place any alcohol within the tavern zone
