Double Door = Pereptuum mobile

[pzfreak]

Hello,

This is rather straight forward.

When you build double doors you need 12 planks, 12 nails, 4 hinges and 2 doorknobs. However when you take an axe and destroy it (you need to destroy piece by piece) it all depend on, i think, skills so you can get much more materials than you actually build it. So if you want you can just build it on top of something and destroy to keep grinding and collect mats if you need.

Maybe it could be limit for output to max input? (so every piece limit would be 1 hinge, 3 planks and 3 nails plus two of them will have a chance to drop doorknob). It is not really big deal but kind of funny if you need planks fast
