I tried disabling autosave, and yes, it didn't crash, but when I try to save, it crashes again on any day, or also when I try to load that unsuccessful save (because it is still created). In general, I don't know what to do; I doubt I can play a mission in a day without saving, because there will definitely be difficult battles that I will have to replay, and playing for a whole day or not closing the game is not ideal(( In general, I don't know what else to do. I hope you can still help me somehow.
