I've recently inherited an experiment that uses UT2004 mazes as stimuli; on one of them, the exit doesn't allow the player/subject to exit--you just bump into a big black wall that says EXIT. I've looked at the maze that doesn't work, and the ones that do, in Unreal Editor and can't find any different in the exit area.
Anyone? Anyone? Bueller?
