[GAMEPLAY] Nunu's snowball never disappears

In the past couple of games I have played against a Nunu, in the beginning of the game, when Nunu makes his first snowball or one of his first snowballs, the snowball never disappears. Usually, Nunu's snowball disappears when it hits an enemy or the wall for example. In my games, Nunu's snowball bugs, keeps rolling on itself and never disappears. The last time it happened to me, the snowball got stuck between blue side's bot outer tower (my tower) and the wall. It even impacted pathing, making it hard to pass through it, but not completely blocking it. Nunu can still keep on making new snowballs and his gameplay didn't seem to be affected by the bug. It seems to only be affecting his enemies.

Steps:

1. Play against a Nunu on summoner's rift

2. Nunu makes a snowball

3. Snowball gets stuck on a wall and rerolls over itself

4. Snowball never goes away or disappears.

5. Pathing for allies (Nunu's enemies) is affected when the snowball is in the way. Nunu keeps playing normally and can make other snowballs.

I remember having encountered the issue two times, but I don't play against Nunu often, so it might be 100% of the games when he is on the enemy team. I asked a few friends and the bug seems to be happening a lot with them too.
