Is your feature request related to a problem? Please describe.

While building a base in a small lighthouse I realized that the lighthouse tower is considered outside (rain starting falling on my bed). Since the tower is fully enclosed with Stone Masonry Floors/Walls, the top of the ladder is inside glass walls, and it is roofed I feel it should be considered inside space.

Solution you would like.

Either change t_stone_masonry_floor to be an inside floor or replace the flooring of the lighthouse tower with one that is.

Describe alternatives you have considered.

Remove some of the walls around the tower to create slits/openings to make it clear that it is exposed to the elements.
