Could you do me a favour and run a TESPCD "Single vs All" check? If you have Beds4Rent as the Single and all your other mods as the All it might well show which mod is conflicting. With that info we can look into getting the information into mlox, as it only knows what we tell it
The only thing in there at the moment is the fact that NoM contains this mod.
I've never used TESCPD before. But here is what I got, not sure if it is what you were looking for.
