No he goes to the stone anyway. Even if brought back by any means, including weaponry, during upload the Boar Stone pig flies forth from the pigpen by clipping through the fencing. It is only resolvable presently by finding another pig from outside the specific spawn point. So far, I will just opt to extend the pen toward the stone, and find more boars beyond the designated spawn point.
