poair building floor mesh can interfere with navigation inside building

[brainiac]

There are two layers of floor and there seems to be some sort of bleed between them.

There is!

I recommend pruning the mesh so that otherwise unreachable areas aren't an issue. This applies to the entire building as well. As it's sitting off the ground on a chainwall of sorts. I don't consider this an issue persay as the tools available make it so you can fix the problem. Unless you're referring to between the two rooms and not the "floor" below.
