I recently acquired this game for the holidays and decided to try multiplayer. As I figured I would need to get ranked, I chose to play against the AI in such a game. However, in my multiplayer game, quite often, after I finish my turn and hit enter to continue to the next season, the game fails to proceed.The players and the AIs are all grayed out in the upper right-hand corner.

I can continue to hit enter, and get the sound that the next season has started, but units do not move and numbers do not roll. The only way I have found to remedy this is by quitting the game (and thankfully because I'm playing multi against AI I don't need to forfeit), and closing it entirely. I have tried running the game though both Impulse and the installed version on my HD, and the same problem happens, but it's not really in any noticeable pattern.
