Exofabs randomly replace or "lose" items that they should be able to produce
Created by: Hoshi-chan
Unsure of the circumstances surrounding this, but I had an exofab spontaneously lose "cyborg right leg" as a construction option earlier.
Another lost the ability to create hyper capacity power cells, despite having created some earlier, being synced to R&D, and the other exofab having them listed.
I understand there are also crazier cases of this, with exofabs producing black gloves and 4no raisins, but I didn't experience anything like that.
