Is this room non-convex, or is there some other reason you have two leaves
for one room?

One thing you might check tho. I had a similar problem if I used the same
plane for more than one surface. I am not sure why. I thought any surfaces
that were co-planar would use the same plane for caching efficiency. This
might still be the case, but I had a lot of problems whenever I tried it.
