Those are easy. There are random errors that I've gotten, such as Vertex point errors that cannot be fixed without a complete overhaul of the map for some reason, Bad UV errors where there is a section of the map that has a messed up UV which stops the game from compiling lightmaps, and is almost impossible to find without redoing the UV mapping of the entire map, and others.

I'm not sure how the game engine will handle them being compiled, though.
