Keep getting a CTD. CTD occurs at the beginning of my turn. Usually occurs when a splash screen comes up (tech, random event, and/or diplomacy). Sometimes I can get through 1-2 splash screens before its freezes then CTD.
I think it has to be tied to a random event, or AI logic as if I start up the same turn enough times, eventually it'll "get lucky" and go through.
I turned on debugging on the BUG menu, and XML bugging in the global defines. Hopefully this is enough to go on. I made some "custom" changes to the XML (not many) while I was playing around, so I don't know if a save game could be loaded.
