Oh, thanks. It certainly seems to be more related to that then. Thanks again. Just saved me a big debugging round .

I think this or the fix for it also broke NixOS. Due to it's immutable structure, it runs steam games in what basically amounts to a chroot with only a more or less complete environment. I will try the exec-path thingy. Edit1: Did not get it to run. I tried adding the path of lib to LD_LIBRARY_PATH ...

Nope. It was a one-time event. Not sure if that's fortunate or not.

Game crashed on autosave. Nothing special otherwise.
