Listen, there are bugs in this game that have been around forever and are STILL not being resolved! I recently had to reset my game about 5 turns, because IF world congress meets on the turn right before a free city petitions your civilization, you will not be given the option to refuse it. You will be stuck with the crap city, and also cannot sell it. How dare you stick me with a crap city that I don't want and can't get rid of! This bug needs to be resolved!
