Load Glitch

One probable cause for this glitch is that when the new map file is loaded, and the old control room map file is unloaded, the new map simply does not know what to put in the doorway. Sometimes this area will have a door that is closed upon returning to it. The door appearing appears to be glitched, sometimes not appearing at all. This glitch can be seen on many other maps on Campaign when in Theater mode, and you fly the camera to a unloaded portion of the level.
