How do I tween currentangle of motor6d?

So, I don't think including a script is any idea because the tweening works and I know that because it works in studio and on everything else, but as fast as I go ingame and try to tween currentangle in motor6D it just won't move at all.

Any help to this? Is it impossible or just me who are dumb?

I appreciate all responses, please try to tween currentangle of motor6d yourself once and go into test mode and try.

I have tried to tween the currentangle of motor6d in multiple different occasions and it always fails. (However it works in studio but not ingame..)
