Similar thing happened for me.

(btw, termbin is friggen awesome!)

EDIT:
Actually, my crash was due to placing a barrel inside a barrel.
My other admin was playing with barrels and added a biometric upgrade to his. But the error log gives my uuid. I'm creating a new ticket, but leaving this here, for historical purposes I guess?

Yeah my issue is definitely not caused from trying to put a barrel inside another barrel so... not quite the same thing.
