What am I not seeing?
Playing solo with Roland Banks.
I'm on act 2a which requires 3 clue tokens.
Hallway has 0 clue tokens
Cellar has 2 (per player, thus 2)
Parlor is off limits until I progress Act 2a with 3 clue tokens.
The attic should also be in play. Note that the hallway is connected to 3 locations, Parlor, Cellar and Attic.
