Summary0007127: Chopping down trees that overhang constructed walls removes the floor from top of walls
DescriptionI noticed this when building a fort with wooden logs on the surface - I noticed that the crowns of a few trees overlap my walls and cut them down. Then I noticed that the floor provided by the walls on the upped z-level is missing in the parts that were covered by the trees.

It's possible that this happens only with walls built from wood logs. I haven't checked with other materials.

Screenshots of an example, before and after (top part of the map):

Steps To Reproduce1. Build a wall under a tree, so that the z-level immediately above the wall contains branches/twigs/leaves.
2. Cut down the tree.

There exists special logic to automatically place 'non-removable constructed floor' tiles above constructed walls when the terrain above them is removed (e.g. when channeling out the natural floor) - sounds like that logic is missing for felling trees.

Hopefully all the instances of this are handled for next time.
