This happens all the time, I have set autosave to every ingame turn to avoid this. No clue what triggers the behavior, except that it can sometimes be avoided by reloading and acting differently: IE moving up instead of down, etc. I seem to be trapped now in a situation where I will crash no matter which direction I move, or if I rest.

Could you upload the save?

Here you go, dude.

Problem persists after redownloading the game ( current windows SDL version), after resetting map and character, it is basically everywhere and makes the game on this version unplayable.

To reproduce the bug just go and walk around inside for a while, going to the next house north triggers it most of the time.
