I always run my maps in Half-Life so I can see exactly how they will work. Anyway, I have basically recreated my scenario in this pathetic little drawing:
http://i26.photobucket.com/albums/c102/HondaKid95/LevelChange.jpgHopefully this will give you an idea on what I am trying to pull here. When the levelchange is supposed to occur, Half-Life does not crash and I get no errors. The map just sits where it is as if nothing has been triggered at all. No loading or anything. I have everything set up correctly but it just wont work for some reason.
Level Change Sequence:
Player opens door (no trigger)
Player enters area of trigger_transition
Moments later the door closes again (triggering levelchange)
Level change fails...
*I have the name of the transition to the name of the landmark
*All names and targets are correct
*trigger_changelevel is USE only
