Could be an auto save, not sure. Around the end turn after a tactical battle, game crashed.
Wasn't doing anything I hadn't been doing for the previous 200 turns.
Memory usage was around 1GB I believe.

I do not have the game installed on C:, instead on D:, this makes some of the errors in the Debug look odd to me.
