when i play planeshift it crashes now and then. That happens like once every 10 minutes or so. Most of the time without any reason, when im just walking around. Also, when i use a portal from the underworld, the game crashes. When i restart  i am at the other side of the portal, or the game says i fell to my death and then i have to get all the way back. It says something happens thats not supposed to happen, and it ask if i want to save it as a diagnostic file. Any others having this, or solutions?
