[GAMEPLAY] Woad King Darius Crippling Strike Bug

I just recently bought Woad King Darius as it came on sale, but every time I would use Crippling Strike immediately after a basic attack, Decimate, Apprehend, or Noxian Guillotine with the skin, the animation won't go off, but the sounds, slow, and damage will still go off. This doesn't happen with any other skin but Woad King. This bug makes it kind of confusing to the players I'm fighting because they would wonder how they got slowed, or even when to counter it like with Fiora's Riposte, except people never know when to counter my Crippling strike because I've got the fastest gun in the West with that ability [lame joke]. I would post a video but my webcam doesn't work. Hope you guys are able to fix this soon. Thanks.
