v50.14 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |
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 Mantis Bug Tracker. Please do not report bugs here; they should be reported on the bug tracker 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).
Some bugs 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.
- Bug 11014: Crash from corrupted military equipment lists
- Workaround: Use v0.43.*

- Bug 9653: Tavern keeper/performers repeatedly serve alcohol until patrons drink themselves to death

- Bug 9438: Caravans/invasions do not come reliably from accessible civilizations
- Bug 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
- Bug 7161: Morale is screwy -- saves demonstrating morale problems in v0.44.03+ requested

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

Lingering bugs
These bugs are not new to v0.42/v0.44, but have been confirmed as still existing. (Year numbers in parenthesis.)
- Bug 1451 (2010): Military equipment interferes with civilian equipment (picks/axes/crossbows/quivers). It is not possible to use a single axe for both wood cutting and combat, or a single pick for both mining and combat. Crossbows in the hands of hunters can also cause problems.
- Bug 94 (2010): Seriously wounded dwarfs sometimes don't get taken to bed.
- Bug 2712 (2010): Weapons, especially whips, cut through steel armor like butter.
- Bug 2780 (2010): 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
- Bug 535 (2010): Equipping weapons/armor on military is erratic. This is a long-standing bug that has been slowly but surely rolled back.
- Bug 296 (2010): 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, they will actually multiply to other tiles.
- Bug 4550 (2011): Dodging into river/lava/pit etc. Apparently, dwarves are stupid. Related: they tend to get thrown off of waterfalls and die from fall damage because they did not account for the current.
- Bug 425 (2010): Dwarves perform cleaning erratically at best -- improved in v0.44.06
- Bug 5986 (2012): Designating large areas for smoothing slows game to a crawl.
- Bug 797 (2010): Animals repeatedly path through "tightly closed" doors causing lag.
- Bug 4065 (2011): Untradeable creatures (hostiles, wild animals) are released from cages when the cages are ordered taken to the trade depot.
- Bug 1582 (2010): 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.
- Bug 5097 (2012): Names overwriting text with TrueType and Bug 5696 strange gaps in report texts.
- Workaround: Hitting F12 to toggle TrueType can often get you around this problem.
- Bug 2587 (2010): Saving fails silently when folder is not writeable (due to full disk, permissions, etc)
- Bug 8426 (2014): Foreign nobles elevated along with fortress nobles, make regular mandates and demands -- fixed v0.44.11
- Bug 8698 (2015): Dwarf entering a strange mood when isolated (e.g. on a stepladder) causes severe lag
- Bug 7444 (2014): Sparring dwarves can knock each other through walls with charge attacks.
- Bug 7872 (2014): Trees grow through bridges, can make the bridge unusable.
- Bug 7760 (2014): Dwarves construct walls from wrong side, wall themselves out of fortress or into alcove
- Bug 7423 (2014): Embark-purchased fruit must be removed from bags before brewing.
- Bug 9440 (2016): 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
