Box mergers

A box merger takes in 2 boxes of the same item type and combines them into one or more boxes. It will place the most full box out of the two and unload the least full. What it’s doing is unloading a box into a loader. The loader box will ether get loaded as normal and you send up with a partly full box and a empty box, however if it completely fills it will break both boxes and you end up with 1 full box and a partly full box.
