[2022] game crashes when savingg

Very unusual on a Mac. I assume like most Mac users you have no antivirus app? On Windows they can get in the way of doing a save (although that would normally obtain for both manual and auto saves).

Has this game always been like this for you? Or it was okay up to some point?

Any mods involved?  

Yes, I'm sure that is the case. Please post the problem save in a new thread in Bug Reports!
