I'm getting a repeating CTD when I encounter a new leader. I think it's Ho Chi Minh, but I'm not completely sure. I've attached the save game and minidump. On loading, one of my Trackers should be active - move it one space northwest and it will encounter a new civilization; crash follows immediately. I think the issue may be in the Extra Leaderheads package. I did update to SVN 2748 and still got the crash.
