Illaoi Bug Hook Thru Knock Up

First time I encountered have this not seen it before.

Cant replicate because no ones on.

most likely something to do with animation canceling.

Im glad i found this in a blind and some pro player didn't die to it

Riot please, I love the game i hope to see this fixed soon. :)

Thanks, Nath

P.s I don't know much about illaoi may be a visual bug if so please make the animation keep going.
