Steps to reproduce:
First, put down some boxes, and connect them with green wire
Next, place down another row of boxes
Next copy the top row of boxes, and paste it over the bottom ones
You'll notice that no green wires were consumed when placing the second set of green boxes (see the toolbar). I was expecting 3 sets of green wires to be consumed.
FWIW I'm playing with SE, as well as a few other mods, but I suspect this will effect vanilla too.
The factory must grow... but still consume the proper resources
