Thanks for the feedback!
I could not reproduce the flipped sides but have show backside on now for future modelling and will report when it happens again (IF 
)
Call me anytime for VR chat or any other chat if you like and we can have a Teams meeting too of course. Or just PM.
Regarding the lockup the help was not on as far as I know. Does it need to be visible to be “on”? If so I will close it.
