I had a really fantastic unit coming out, that had Arcane Armor and a Legendary Weapon (I chose the Axe with Backswing - second chance if first dodges) from completing the Arena, and a horse, Two Strength Traits, 1 Constitution Trait, a whole lot of accessories, and I was going to wipe out Gilden, which I had let get about three quarters as powerful as me.  However, when the game crashed, I found that the two autosaves and the manual save always crashed the game, so they must be corrupted.  It seems late game with big units and big empires you can keep playing (if no significant other programs running) but when it crashes the saves you have are likely to be corrupt and crash the game when you try to load them.  Can you have a look?

Last Manual Save and Two Autosaves (Probably Corrupt):

Hope these help!  I think the game is unrecoverable, but if I fluked it and it's fixable, it would be great to continue the game.  But I do hope you can make late games with big empires not get file corruption, and that you can fix the problem for future games.
