I've been unable to reproduce this behavior on this level a third time.
This is indeed a weird one. I thought for sure if I managed to get it happen twice that it would happen reliably under the same circumstances.
It just so happens I'm set up to record play sessions, and I enjoy lounging around in Mr. Friendly on my time off. The bug happened on a completely different level just yesterday (at the time, I thought I had reproduced it already so I've forgotten where exactly it happened) It seems to be quite rare, but I'll try to track it down and hopefully provide reproducible circumstances and video evidence to go over.
Thank you for working with me on this.
