Tweening Rotation Messes With Projectile

I am making a magic game, Im working on a projectile that moves forward and has rings rotating around it to make it look cool. Im planning on using tween service to rotate the rings. But when I use tween service to rotate the rings, it makes the whole projectile stop moving. I think this has something to do with the welds in the model.

  • The Model , Wind ball is the primary part, the small and Big particles are the parts rotating around the wind ball.
