Once again, I enter the volcano with Wilbur, walk around a bit, then game crashes to desktop. Repro steps are from what I remember. I don't have a concrete set of steps, but this is the second time the game crashed with the similar set of steps. I do have a backup of the game a few (game) days before the crash if you are interested.
Attaching the game log, there is no entry in the windows event log or a minidump I can see.
1. Play as Wilbur. 2. Enter Volcano 3. Open map, Walk around a bit so that Wilbur runs 4. Open map again while he's running. 5. Close the map, walk a bit. It crashed here.
