As an addendum, I was able to get teleporting to work using PartiesToTriggerWithMovie, but the dummy was still not being recognized as a player, one my hand placed temp characters had to do it.
I WAS able to get it to work for the dummy by using TriggerRegisterForCharacter in the INIT section. But that shouldn't be necessary, TriggerRegisterForPlayers should work.
Perhaps it's something wrong with the shared dummies.
