The tutorial worked out great! but there is only one problem, when I try to actually build the unit from a city, or change a city's production, before the list pops up to change it, the game crashes, no warning, no error screen, just crashes. I have no idea what could be causing it. I've run it in debug mode, the unit itself works fine, but the game crashes when i build a city and asks what to produce. Does anyone else have any ideas?
