<G8> Scoring Objects that leave the playing field will be promptly returned to the playing field in the same Zone as the Robot that ejected the Scoring Object.
If a robot in the Haning Zone throws a Buckyball and knocks a Large Ball off the top of a goal (Stashed) and it falls out of the playing field (leaves the playing field), will the large ball be placed in the Haning Zone or the Goal Zone?
In the case that a Scoring Object exits the field as a result of contact with another Scoring Object, the Scoring Object that exited the field will be returned back to the Zone it was in prior to exiting the field.
In the example you have stated, the Large Ball would be placed in the Goal Zone.
