i too am also noticing this.
i didn't know it was the Fog of War option.
Have you tried turning it off before the game ends and seeing how it loads in the following mission?
I'm sure you can't fix every single little bug but this is just one of those slightly annoying issues.
anyways, thanks for the great product!
just tried: it does crash even if you turn it off before the end game

I think in the past couple days there have been some other reports of CTDs that it's not a one user issue mishandling the trainer.
Seeing how you aren't seeing the CTDs, perhaps this is an isolated case regarding certain systems or settings.
I've verified the files and reinstalled the game for good measure yet the FoW feature seems to be the trigger for the CTDs (For me at least). First game was fine, the second game is always the issue.
Could this help narrow down your search?
