Static Objects Not Appearing

[Thief977]

Been working on a starting room for my map, and I have a split sections that goes down to a cellar, using the objects and textures from the cellar_base folder. The rest of the map is made from mostly mansion_base, so that might have something to do with this:

Any time I load the map, the cellar stairs, walls, ceiling, and floor don't seem to load. They're just not there. I had see through the areas they are, and fall through the areas they are.

Any help on this would be greatly appreciated, as I can't continue until I get this to work.
