[GAMEPLAY] Shaco's W bug in (Live Client) 5.22

First, I want to say that I'm french and I will try to write in English the better i can.

Hi. Today, I played in a normal 5v5 game and i was with Shaco in jungle. In mid, there was an Heimerdinger in the enemy team and he took a Zz'Rot Portal. I tried to gank in midlane to help my Lux and i did a W nearby his Zz' Rot Portal and, at this moment, a Zz'Rot's minion spawned and my W make fleeing the minion. And he stopped to move and stopped to attack but I was able to hit him.

So, with a friend, we maked a custom game to look if it was just a small bug for just this game. Here's a video i took about the bug : League of Legends - Shaco's W bug in 5.22

Thanks for reading this small text.
