--[[ Remove broken double plants caused by v6 weirdness.
v6 might break the bottom part of double plants because of how it works.
There are 3 possibilities:
1) Jungle: Top part is placed on top of a jungle tree or fern (=v6 jungle grass).
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
3) Mudflow: Same as 2) ]]
