Describe the bug
I was messing around with a frame machine I built and then I crashed.

To Reproduce
Steps to reproduce the behavior:

1. Not sure how to reproduce but my frame machine had lumium hardened glass and when I logged back in some of it disappeared so I'm guessing that was involved somehow.

Expected behavior
no crash
