For whatever reason, I was playing on emperor as the spanish, and all 4 other civs were teaming up to keep me shut into only one city. This was screwing up my plans, as they had armies on just about every workable tile. As a solution, I planned to build the Manhattan Project and usually people will want peace with you because they are scared of you. So I built the Manhattan Project... and it spawned no ICBM. At first I thought maybe a spy got in and stopped production or someone else made it first, but no, the wonder was right there in the buildings list, but no ICBM. Has this happened to anyone else?
