I have been playing the game for most of the night, an easy simple game so I get used to it. Three times the game crashes when I hit the turn button. Usually if I load back from a previous Autosave that was far enough I can keep going (I need to load back 10+ turns to usually avoid a crash). I did not have a nearby save for the first and second one. But now I actually have a save file on the turn which the game crashes, loading that file garentees the game will crash when I hit the turn button.
I do not know what to do besides loading back an older autosave and keep playing from there hoping I do not reproduce it. I am keeping the save file of the crashing turn if it has any use.
