You are trying to do something special there. On that spot, you both have a door and an invisible actor. If you drag the invisible actor away, the door works fine.
I understand what you are trying to do. First get some text and then be transported to another level. But you cannot make that work currently. I probably need to introduce either:
– Screenplays on doors, so you can add some actions before going through the door
– Loading a new level inside a screenplay, so that an actor can send you somewhere else.
Probably both would be best ;). I’ll think about a way to quickly implement support for this…
