I got similar problem, my PRAWN had been rotated and got perma stuck on one side. I have no idea how to turn in back since even grappling hook doesn't change prawn's orientation. I manage to get on cyclop but it was very painful.
I put couple things, like aquarium, fabricator, some unnecessary stuff, and when I finally put most important power cells charger I heard very unpleasant sound and short shake - overload! Thought whole cyclop will go down for a sec.
