The recycling furnace fucks up hard when it tries to accept plasma sheets
Created by: Probe1
It will just sit there if you involve plasma sheets at all. It won't process any recycled materials inside the furnace and turn them into sheets. It won't accept any new objects to be recycled. It just sits there. Removing the offending plasma sheets fixes it.
This worked fine less than a week ago so something recent has fucked it up.
