[GAMEPLAY] ARAM Permanently invisible Shaco

I really wish I had taken a screenshot of this, but I literally just played an ARAM game as Shaco. I wasn't paying attention to what I was doing, I think I ulted, then Qed. From that point, I became permanently invisible. Nothing I did, neither attacking, using abilities, nor standing under towers made me visible. I was able to basically have free reign of the game. I mean, if this is a new feature for Shaco, tell me. I'll be delighted to play the new OP perma-invis Shaco, but otherwise, this was kind of a ridiculous incident.
