I was wondering if anyone has had problems with the game crashing during invasions. So far I have had 3 invasions. The first 2 crashed to desktop and when I loaded the save the invasion played out fine. However, this 3rd one constantly crashes. These invasion crashes have been my only issue. Which sucks because I love the invasion aspect of this whole deal. Please let me know if this has been an ongoing problem. Thanks.

P.S. I am in the late game now. Small map just to learn the ropes and two civs.
