What steps will reproduce the problem?
1. I opened up Bigwigs Firelands encounters options while sitting in town, specifically for Staghelm.  I unchecked some options.
2. After a bit I noticed I had 4 errors in Bugsack.
3.

What is the expected output? What do you see instead?

What version of the product are you using?
r178

Do you have an error log of what happened?
