v6 might break the bottom part of double plants because of how it works.

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) ]]
