Rotors begin to rotate automatically after ~5min idle

[TPenn]

Hi,
Just started the community preview, and taking my time inspecting the cockpit when after 5min idle, I notice the rotors beginning to rotate, very slowly.

With the engines off and no power they shouldn't move even under gale-force winds, but I stepped out in case to see if they'd continue spinning and they instantly stopped.

Hopping back in and waiting another 5 min produces the same "haunted" rotors behaviour!

to add to it (possibly separate bug entirely):
after starting the rotors properly and turning off the engine, from inside the cockpit the rotors spin indefinitely. as soon as the player exists they spin down. too conspicuous of a coincidence...

if there is wind you have found your ghost apply rotor brake and see what happen
