Crash to desktop

I have a game where I have the "Save after every turn" option enabled.

When I return to the last saved, it crashes after the same battle everytime. Figured this could be used to maybe debug an issue. Just hit end turn and you will see what I mean. The Abaddion Enclave is in a non-agression pact with me, and choses at the end of this turn to sneak attack me.

here is the saved game files.. in case anyone wants to try to figure out whats happened?
