Machine crank/handle

[LSunday]

Like above- The crank breaks if you try to use it after the machine is completely fixed.

So, for it to break, you have to do either the lever or pipe thing last, and not have propped the door open with boxes. (I was too scared a monster would enter from the main room, so I preferred to leave it closed).

It comes from having more than one way to solve problems. Occasionally you get items that you didn't have to keep.
