AI and Custom Maps

Hi:). I've done a search and only found info pertaining to 1.1 on this, but when i choose one of the in game custom maps, set my opponents to bright or intelligent, they do nothing to try to colonize. I've tried a couple different ones and always the same. I even left a planet uncolonized for while to see what happened. Finally got one of four(four corners map at the time)to colonize a world. I was wondering if it had to do with not getting the starting colony and survey ship. Thought maybe that was screwing up the AI. If it was other games I'd put it as a map made for multiplay, but of course thats not the case here. Has anybody else had this or gotten them to play right on these maps. If so what settings did you use? Thanks for any help.
