I think I've correctly followed the directions about how to generate and post an error log.
Should I have posted the actual information from the log in this post?

Hmmm. Can someone tell me how to generate an error log?

I'm not sure how to check whether I have an old Squinge hack or something else that might be causing this. It wasn't happening until I installed the Mansion and Gardens stuff pack so I didn't think that it would present any conflicts.

I'm having the same problem. Hopefully someone more awesome than us will come along.
