Whoever's helping test, please try the following.
Do the quick game/etc settings I describe with the previous attachment. However, disable TBC with an _ in front of the folder name. See if the crash happens with only CiVUP enabled... we can start narrowing it down.
Did, and it's not fixed. The game just froze when I ordered my scout to move, through a city-state's borders, next to another civ's borders. I think it has something to do with either revealing fog or civs' borders because those have been the common factors in this type of crash for me at least.
