In the Mediterranean Defense game, I had all but 3 cities under my control. They were all sitting at about 30% assassin control, except for Alexandria which had 50% and Marseilles which had 47%. Then I quit SP and played in MP for about 3 hours. When I went back to single player again, I found that all my cities were under seige, except for Alexandria with 6% and Marseilles with 4% assassins control.

WTF? Is this supposed to happen? I thought it was a bug at first, but no one else seems to be having this problem. It seems a bit unfair, since the bank didn't give me any extra money for the time I'd spent in multiplayer. The only thing I can think of that may have triggered this is the fact that I deleted the 1.2 patch to get the Sage trophy (which I'm still saving for *sigh* I wish I hadn't bought all the landmarks), but none of the other players who did this have reported the problem...
