I think I screwed up the elevator machine.

[Kein]

I turned the burner on before I pulled the lever that makes the wheels turn... Now it's not working. The other two puzzles are perfect and have been solved.

...Please don't tell me I need to load a save and not turn the burner on. I'd have to re-do the storage level. Dear Lord, please do not tell me that.

Well, in any case:
