Infernal Nasus AA and Q Animation Bug [Gameplay]

Since about 5.10 Infernal Nasus' animations have been bugged and look very choppy and not fluid like they used to. I know I am not the only one with this problem, but it might only have happened to a few people.

Here's a Youtube video (not mine) that depicts the bug. https://www.youtube.com/watch?v=ygZ6U5LO9KI
