Goth Annie Permanent Passive Visual Bug
So this happened in one of my ranked games (EUW). In the clip you can see how annie got polymorph as she got her passive stacks, which I think is what caused the bug to begin. From that moment on throughout the whole game, Annie had the passive circling around her permanently. Note that the stack bar itself and the actual ability were working as intended, but visually she always had her stun up, which nearly lost us the game as we used a few flashes thinking she had her stun when she did not.
