Here's my situation. I have a character with level 2 Viking Wizardry. I'm using Skatha's Roots to kill everything. However, sometimes I will cast it on a diggle, who will then burrow. My game crashes immediately to 5 turns after that. The .dmp file produced by the game has the exception information as "The thread tried to read from or write to a virtual address for which it does not have the appropriate access." It might be a different cause, but that's the correlation I've seen. Any more information needed?
