a441 said:That can happen for a lot of reasons. The most likely is you've been careless with linedefs.
Linedefs aren't "just lines." Each one stores a number for the sector in the front of it, and (unless it's one-sided), the sector in the back. If you drag lines around, you can make those numbers incorrect. In addition to visual glitches, this often causes the problem you describe.
Screenshots are generally useless in this type of situation. Post up the wad, though, and someone might be able to help.
