This happened recently (right after our version hit 22.214.171.1245. Basically I would host a match with my friend over the internet, we'd get to the first turn, and then once I was done the game would continue to do turns without my input, and never bring up the "Click next turn" it's like it got stuck in a for loop without letting me do anything. The city would expand it's area, the energy would keep accumulating (as well as the culture) and it would just keep going and going and going. My friend and I killed our local cache and re-downloaded but now HE gets the problem instead of me. When he gets the unending turns i can't do anything (like I can't get to the menu by pressing ESC). And he has to quit to main menu before the game let's up and detects the last human player has left the game.
