So I'm 80 turns into a legendary campaign, and every time it's loaded it's during the AI turns. Every time it gets to my turn it crashes to desktop. I've searched high and low for a fix for this and even tried editing the save file.

I don't mind the gameplay difficulty of only one save, but when you can invest all that time into a campaign only for a bug to effectively corrupt the save greatly disincentivizes me to play at that difficulty. If there were two saves then at least you'd have the opportunity to play the turn in a different way as to affect the game RNG and states so as to prevent whatever event is causing the crash.

I might be misremembering but haven't there been previous titles in the IP that have two saves for legendary difficulty, one that's always one turn behind?
