This is a problem that I have only had with one ongoing saved game.  I have played other games since then without a repeat. I also checked to see if anyone else had mentioned it, but did not find anything, so I will describe the problem and if anyone has a suggestion or comment please feel free to chime in.

In a game of Rebellion, 1 human vs. 9 AI players, the computer has started locking up for 10-20 seconds.  Then it comes back for about 10 seconds, then locks up again, then releases, then locks up, etc. etc.  I have tried updating both the game and the computer, and rebooting as well. Same problem, different day.  We are at the mid-game point (5 players and pirates gone, and this issue only showed up about 15 minutes ago (game time).

I could just abandon the game and move on, but it was just getting interesting.

I have played larger and longer games and have never had this happen.  I am playing another similar game right now, and have not experienced the same malfunction.  Any thoughts?
