Odd bug. I built a city up north of where my first city was and my sovereign moved to the space below it. Then I hit next-turn. Then I tried to move the sov up to the left towards the little nook where the fire shard is at and the game just froze. I went to task manager and the game was sitting at 24-27% CPU usage (on my 4-core Phenom) and was chewing up about 6MB/sec of memory. When the memory footprint hit 1,703,000 MB, it crashed. However, it did not produce a valid dump file. It was 0 bytes. This was around turn 40-50.
