Mesh problems in tunnels

[danime91]

I've discovered that in some of the subway tunnels, like the Marigold Station or North Seneca Station, there are huge gaping holes in the floors and walls where the meshes have apparently been moved over or something, and my character and NPCs will fall in whenever we try to walk over them. Which mod could be causing this? Here's my mod order btw.
