Hi @Ezekiel88
The problem of your simulation is again the geometries, that two faces from the block of room_8 leading to nonconvex geometry.
For a test, you may use a very simple rectangular cube and see if it is working.
Then if you need to have more or less the same geometry, you need to break your space into two very convex parts.
Another issue of your simulation is that all of your geometries do not have the same reference elevation. For simple projects, it is ok but complex one may bring some challenges
