My wife and I are playing in multiplayer mode, hybrid. When we go to war with each other, the game goes into sequential mode. However, we cannot ever get beyond one turn. Once the person who can play ends their turn, their computer goes into a loop where they get more and more credits and culture, and the other person never can start their turn. We've tried a whole list of things, because we'd like to be able to play MP and go to war with each other, but every time we go to war and it goes into sequential mode, we get stuck unable to continue the game.
