errant, In this game I'm playing, I found a minor treasure at the bottom of an elevator shaft. You can only find it if you take the elevator up, then jump out a window, and thus can look into the open elevator shaft. There is also a button there. It makes the elevator go up/down
There is no point for this button to be there in the bottom of the elevator shaft unless... A playtester sent the elevator down, jumped off, and got trapped under it. Environmental storytelling
