I feel that this shouldn't be a valid turbine:

Also, the game crashes if I slap a controller against another controller that hasn't yet had a chance to (re)form the machine yet:
crash-2022-02-17_20.52.11-client.txt

*a couple of crashes later* Actually, I think the crash might be when I try to place a controller but I'm in the way. 🤔

Yup, it should not be valid.
