I've set up a game to test my mod to see how the AI deals with the new features. But upon starting, I can't choose production for my city! I can enter the city screen with no problem, but nothing happens when I try to select production. No list of units or buildings shows up, nothing. I later figured that I could make my capital city a puppet in World Builder, so it will choose production for itself. That seemed to work fine, the city started to build on a Market on the first turn. But upon hitting Next turn the game crashes with the generic ".exe has stopped working" message. I'm guessing this is part of the same problem. Does anybody know what usually causes this problem? From what I know, it happens when there are too many stuff to select from, like 50+ Units or Buildings to be built, but that shouldn't be a problem with this mod. I'm left completely clueless.
