After playing for what seems to be about an hour or so I get a crash to desktop.  This seems to happen almost every time I play and makes getting to an advanced part in the game near impossible.  Love the game so far, but would love to be able to get more than an hour into the game.  Also if I reload the auto save I get the same thing every time, so I have many one hour games because I can only play until it becomes corrupted then I have to start over from scratch.

Here is the dump file. http://pastebin.ca/1927860
