Shaco clone bug

In my game I have experienced a bug with Shaco. I am a Shaco main and recently in one of my games, when I was using my clone and recalling at the same time, it would cancel my recall. Never has this happened to me in any of my games and I dont think Riot has touched Shaco in awhile. To reproduce this bug all you have to do is ult and start channeling your recall, then redirect your clone and the recall will be cancelled.
