Annie Stun Visual Bug

I was in a regular game dominating mid lane with Annie. I looked down, "Good, my swirly swirl stun is up." I walk to the creep line, enemy champ walks into range. TIBBERS GO! Enemy walks away...I look around confused. Swirly swirl still there. I continued to play the game and the bug was still there even when I died. Nothing made it go away until I just eventually finished the game. Me being a pre-patch Annie, I check the avatar visual aspect more than the counter below my health and mana bar. Just wanted to see if anyone else had this problem and report it so Rito can fix it.
