Orianna Ball Disappearance Bug

When I was playing an ARAM as Orianna on Patch 7.3 (Not sure if it'll happen in normals) My ball suddenly goes invisible when it auto-returns to me, or if I shield two people, and also when I spawn. The only way I was able to see my ball was when I Q, but a second later it disappears as well. You cannot track down the ball after you Q, so when you Q you have to immed. ult otherwise it'll disappear for good until the next Q.
