I originally though that the Shrine/Storeroom door didn't open, but when she completes the Kings Storeroom, she glances at the door, but goes to the Medusa's Lair instead. When she runs to the Medusa's lair door, Kirk says something like "Oh, she's going back?" which makes it seem like the door opened. But that could just be Kirk being Kirk. If the layout didn't have the Shrine/Storeroom door open, they should have atleast kept the Observatory/Lair door locked. That would've been an interesting layout. And yeah, the Belshazzar kids got screwed over. How could they overlook 2 production errors that made winning literally impossible?
