I think that link speaks for itself. It began to do that since i accidently used the node builder to do something. What's wrong and how do i fix it?

EDIT: I fixed it, somehow. No need to reply.

You'll see this happen again, because it happens all the time. I've got a huge level where about 10% of the floors are missing, same with ceilings. Don't worry about it.

Choose a different nodebuilder!
