In the Shattered Bonds scenario, there is a dumbwaiter in the basement that leads to the attic. One of our players took that dumbwaiter to the attic where a monster spawned.

She ran away back down the dumbwaiter. We hadn't revealed any of the other tiles leading to the attic, and we weren't sure what to do about monster movement for the monster in the attic. It doesn't seem like it would use the dumbwaiter (which requires interacting with the Interact token on the board), so it was trapped there.

Thoughts? Do we just get to leave the monster there until we reveal the tiles leading to the attic?

Thanks.
