I'm playing civ4 on Prince, and I have 8 cities and six courthouses, but two of my newest cities have the Forbidden Palace icon greyed out (while all my other cities have a bright icon and will allow me to build FP in them). Naturally, I want to build in one of the cities that will not allow it. Is this a bug in the game, or is there a reason why some cities don't allow FP construction? I can't find anything in the manual or the civpedia and would certainly appreciate advice and assistance.
