Hello, I think I mentioned before that I'm somehow being attacked through the walls even though I shouldn't be, right? Well, I also have it set so that the terrain is not_flyable and blocks_sight. It seems, though, that once I get a flying unit the blocks_sight thing is ignored and I can shoot my opponents back through the wall. Is this intentional? If so, could you add another version of the blocks_sight flag that will also block flying units from seeing/attacking through a particular unit/structure/terrain?
