when i try to compile the file i get
Error: displacement found on a(n) func_detail entity - not supported (entity 158, brush 0)
after moving that back to world, i then get
Found a displacement edge abutting multiple other edges.

Displacement 142 has bad geometry near 176.00 1316.81 -64.00
Can't compile displacement physics, exiting. Texture is NATURE/DIRTGROUND002
furthermore you have a big leak in the roof - since you have no skybox and a big gap in-between some of the geometry at -631,710
