Orianna Missing Ball

I was playing Orianna on ARAM with the Bladecraft skin. Whenever I would Q the ball towards an enemy/minion or E the ball to an ally or myself the animation would go off applying the ability, but the ball it would disappear. At times when I would Q the arrow that normally shows where the ball was would not pop up sometimes, leaving me to either W to see where the ball was so I could grab it or E it to someone. Even when I would walk around normally when the ball was supposed to be hovering around me it would suddenly vanish. The next game I got Orianna I used the Gothic skin and the ball never disappeared.
