Alright. So I'm playing with 5 AIs and myself. One of them decides to hand their entire civilzation over to the terrans. The message said they were going to do it before they instead became annihilated. I figured, ok, on with the game. Then later another AI gives itself over to the Terrans. They had the most area claimed by their influence and many planets. They just said, oh, hey, we're giving ourselves up to the Terrans. Does this happen often? Out of the blue? I realize its my first game...but it seems QUITE odd.
