Ok im making a SWBF1 map using some of SWBF2's ODFs and MSHs, but im having some problems with some of the models.

I was testing the map and I walk onto a seperate prop/building and fell right through the floor (this does not happen with every prop/building).

I don't know if it has anything to do with the (msh.option) (.msh) or (.odf).
Could someone help me out?

(One of the props is the Cor1_bldg_library_upper.odf).
