This is because the schematic might be placed even if some nodes of it
could not be placed because the destination was already occupied.
TODO: A better fix for this would be if schematics could abort placement
altogether if ANY of their nodes could not be placed.
2) Cavegen: Removes the bottom part, the upper part floats
