What on earth does this message mean, and what triggers it?
I don’t know everything that triggers it, but one way to do it is if you’re doing a “Take all” but processing one of the takes moves you out of the room. e.g.:
[code]Test Chamber is a room. Expellatorium is a room.
A portkey is in Test Chamber. A wand is in Test Chamber.
After taking the portkey:
say “You are expelled!”;
move the player to the Expellatorium.
test me with “take all”.[/code]
Ah, okay.
