Kayn bug?!?!?!?!?

So there is a bug with Kayn where is Q cooldown will be consumed yet he will not do the first dash or the spin at the end. Kayn will just nudge forward and the cooldown will be consumed I have had this 7+ times in the last 3 games of Kayn I have played. This bug normally happens when I am using W before I Q or when I am W then Qing out of a wall. It has cost me many kills and caused me to die many times [zombie-nunu-bummed]
