Zac Elastic Slingshot bug

In the past couple of games, i have been playing against zac, and whenever they gank from fog of war with an elastic slingshot, the model doesnt do the animation at all (not even the landing animation), i have restarted my client during one of the games, and that didn't fix it either. I was just wondering if anyone else has had this problem, cause it just looks like an idle Zac sliding across your screen from nowhere.
