Thanks for the report, could you upload your save file and mods folder so I can try to reproduce it?

My last auto save was was quite a few minutes prior last night, i attempted to reproduce it myself but i could not duplicate the crash, apologies.

I attempted again this morning with current save after reading your reply, and again i could not duplicate it.

The original autosave prior has been overwritten. If you would still like a save file, ill upload one.

Yeah it's only really useful if I can reproduce it. If you happen upon the bug again please upload the latest autosave and describe how it happens.

In the mean time I have some ideas of what it might be that I can work on.

Released v0.3.4 with some better handling for weird stuff happening to surfaces. Hopefully it will prevent the bug you were encountering.
