[Gameplay] Zed becomes transparent after activating his ult, just for the player

(Sorry for that no screenshots or such are included) In the game I discovered this bug, I played as , used the ult to enemy . He used when I was rushing toward him. After that, became invisible, ONLY FOR ME. The other players could see my champion and attack or use skills on him. One fortunate thing was that I could move him. I couldn't check if I can attack or use skills when the glitch occured. Plus, became visible again after I was killed and respawned. It may not be a frequent bug. However, since it would be critical for all Zed players, it has to be checked in detail.
