Controller object does not always attach to the hand that picked it up
When taking a controller object from the player menu, it will sometimes attach to the opposite hand (ex.: go to the left hand when picked with the right hand).
This can happen even if the hand already has a controller being held, allowing the player to create infinitely many extra controllers, lagging the game down for other players.
Letting go of the bundle of duplicate controllers will leave them floating in the air as per another bug.
