// controls the state (2408) is reset when the player goes down the stairs.
// Furthermore, the room's initialization script disables the stair exit
// control (4652). This leads to an impossible situation, where all the
// exit controls are disabled, and the player can't more anywhere. Thus,
// when loading a game in that room, we check for that impossible
// situation, which only occurs after the player has moved down the stairs,
// and fix it here by setting the correct background, and enabling the
// stair exit hotspot.
