It's been a while since I had the time to play a bit of MTW but now I have. So installed MTW + VI + VI patch + XL mod for a good old early campaign with the Volga-Bulgars.

I play a few years and then I stop, so far so good. Later, I return and start MTW. I load my latest save game but the moment it should go to the map I get a CTD. This is the case with every savegame I try.

What could be the problem and what can I do about it?
