Feature Description

Better compatibility with mods like TreeFall or Trees Do Not Float

What Problem Does This Solve?

When I use the mod TreeFall, it leaves leafs floating.

A Solution You'd Like

If there is a way to make leaves from Terra trees decay like normal, that would solve the issue to a reasonable degree.

Alternative Solutions

1. I could open an issue with the creator of TreeCutter about this.
2. You could also require all leaves in trees to be directly touching another leaf.
