[GAMEPLAY] Invisable Orianna Ball

Recently when I was playing a game as Orianna, about halfway through my game The Ball, when above my head, became invisible; I still had the defense bonuses as if it were there, and when I moved it with my abilities it appeared and moved as normal. When I would activate my E shield or move outside the lease range however, it would snap back to me, but become invisible. None of my teammates were able to see it above my heard either. Obviously this does not quite affect actual mechanics, but it could become confusing if it happened in the middle of a teamfight or to a newer player.
