If you have a VMK pass and you are teleporting at the same time as you're supposed to teleport to the host room, the pass will vanish. I was 1 in queue, riding my ride for the competition, and it disappeared. I relogged in and it said I missed my spot in the queue. Sent a CFH but not expecting to be let in.
So never try riding rides or teleport when you're close to entering a host room.
