Major Gibber breaks when grinding a corpse

[Superlagg]

When you turn on the Gibber with a dead guy inside, it grinds em up just fine and spits out a hunk of meat. However, if you touch it afterwards or while it's running, it will forever state that it is still in use, and become unusable.

Sometimes, you can spam click on it while it's running to make it spew out lots and lots of meat. However I have no idea how to reproduce this reliably.
