Can the goal objects be moved?
As long as the goal objects are wholely within the workshop, you can move them. There is a physics glitch that allows the user to move the goal piece to anywhere in the arena if the goal piece is not fully in the workshop. See Four Balls, where the second ball may be picked up by the right-hand joint. If placed within the workshop, it may be moved around within the workshop. If placed outside the workshop, it may not be moved again. Usually moving such a goal object to within the workshop is permitted.
