[Gameplay] Darius Double Q Damage Bug

Edit: You can see the CD bar on the actual website.

I was playing bots as the new Darius just for pentakills, and I noticed that in this clip his Q goes off twice. It happens about 8 seconds in, right as I kill nid and ali.

Its definitely a bug, the damage applies twice, and it even shows that its on cooldown when the second swing goes off, and it reverts the cd to full time.
