I was rapidly opening, closing and reopening the Grimoire object looking at what I needed to pull out of chests for a recipe when a shutdown occurred. I believe the wand I was using disappeared at the same time but I didn't notice till later so it might not have been involved.

This crash should be fixed in the next release, currently planned as v4.0.6. Thanks for the report!
