Orianna Ball Disappears in Aram

I was playing a game of aram as Orianna. After a major team fight, i had just spammed my spells, and when i backed away frm the fight, the ball had disappeared. It wasnt anywhere on the map, or on any other champion. I used the shield ability on myself, and the translucent ball appeared around me and i gained the shield, but the ball itself still hadn't appeared. When i used q and e to move the ball it reappeared and worked fine. I guess it's just a visual issue, but i thought i should bring it up.
