Annie's Passive Stun Visual Bug. [Gameplay]

I just got done playing a game as Annie and I noticed that throughout the whole game the swirly winds that go around her when she has 4 stacks of her passive, which notify you that a stun will happen on her next ability, remained around me the entire game, regardless of the amount of stacks I had. It stayed like this the entire game. It was not like this once I spawned and started the game, but once I reached my 4th stack the first time it seems to have gotten stuck. It is only a visual bug as it did not stun targets when I had less than 4 stacks.
