Summary0006117: Vermin can only escape from artifact animal traps
DescriptionPart of the logic for vermin attempting to escape from animal traps includes a check against whether or not the animal trap is an artifact. This check appears to be backwards, however - as a result, a trapped vermin can only escape from an artifact animal trap, and a non-artifact trap will be able to safely contain any type of vermin.

This bug appears to date back to at least version (which is where I initially found it).

This applies to all types of containers - in Fortress mode it's only animal traps and cages, while in Adventurer mode it also includes backpacks, quivers, waterskins, bags, barrels, and any other type of container you might find.

I can confirm that this happens with cages; I recently had a half dozen small tame creatures escape from an artifact cage immediately upon being placed within it. I have, otherwise, never had a tame creature escape from confinement.

The following binary patch fixes this problem in Win32 v0.34.11 SDL:

This patch could lead to hilarity with Elven caravans - they bring all sorts of vermin in wooden cages, and any with [GNAWER] would immediately escape upon arrival.

I can confirm Quietust's prediction of hilarity: gnawing vermin brought by elven caravans escape immediately upon the caravan's entry, with this patch in place.
