I was having a reliable crash at this point in Shadow Pass while on the final part of "The Killing Ground" mission (helping Trav kill the Tuatha general). I would reach a point where Trav and Cydan were fighting a Barghest when I got the crash message shown. When I pressed 'yes' to send a bug report the game would crash to desktop. This happened on both the online and offline versions of the game. After restarting the offline version, I had a wild idea to turn off 'Sphere of Protection'. I was able to get to the general's camp and beat them without the sphere. Everything seemed to be fine and I was able to play a bit more with the sphere on.

Sorry, can't figure out how to attach image file.
