Weird critter movement/behaviour

[Janiczek]

This differs wildly for different critters, but overall the NPC "idle" (non-combat) movement seems wrong compared to the official game binary. For example the rats in the video below: they try to move, but most of the time they don't make it and snap back to the original hex tile.

The video is made with the speed patch (#174), but the same issue can be seen with on main.

Geckos seem similarly affected: they mostly stay stationary (eg. in the Klamath south area with the still), while in the original game they would move around a lot.
