PBE Udyr Bug

I was just playing a normal game on the PBE server, and I had not noticed this untill in later game, Udyr's bear stance auto attacks were bugging out and resetting themselves or not even hitting the intended target. And when it does hit it's actualy able to infinitely stun the target. It's worked on jungle camps, creeps and most importantly champions. Although it was kinda hilarious to see at the start it would get pretty hectic if it stayed unnoticed.
