Hey all. I apologize right here and now for being a noobie but we all have to start somewhere. I'm playing the Civ III vanilla edition (I know, I know, PTW, C3C expansion packs, CIV 4...). Right in the middle of building a wonder my annyong advisor tells me Rome (or whatever city) can no longer work on it and the city is switching to something else. Why does this happen? How can I avoid it? HELP!
