[Gameplay] ARAM Snowball issue

This has happened twice to me when I attempt to use the snowball summoner spell in ARAM since the latest patch. While attempting to aim the snowball at an enemy champion my cursor seems to glitch and lock on to that champion and when I try to cast it, the snowball goes the exact opposite direction (behind my champion). I have had this once as Poppy and once as Annie. Shortly after this occurred in my Poppy game, the game bugsplatted.
