I have been working on a map for a while now. Yesterday I decide to raise some of the ceilings in a few rooms. I only extended the wall and ceilings in the rooms directly up. When I went to compile, of course, I have a leak. I quadruple checked all the walls for leaks. I even overlapped all the walls and ceilings just a bit to make sure. I have no entities out side either. I also loaded point file, and it looks like a huge red scribble all over the map, that I can't even begin to understand. Is there any other reason why it would be saying there is a leak?
