Caitlyn and Tahm Kench bug

Just a heads up: I'm sorry for such low quality.

So, basically what's happening is Cait is preparing to fire her Q, but right in the middle of the preperation, Tahm eats her. You would think this cancels the Q. But instead, the Q still fires. I tried to slow it down so you can really see it, but this particular bug happened multiple times this game.
