--[[ 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) ]]
