[Gameplay] Udyr aa'ing from 400 range away after Charm

So I was playing a match. They had an Udyr jungle, I was Ahri mid. Udyr ganked me at level 3, I was without flash from his previous gank but I was confident I could get away if I just charm Udyr and Q away. So I charm him, he's walking up to me slowly, unable to act, and all of a sudden... As soon as Charm ends, he literally auto attacked me from 400 range away. I had a friend witness this from spectate. This ultimate led to me dying, because his 400 range auto attack stunned and killed me. Pretty serious bug if you ask me, a Charm allowing Udyr to auto attack from 400 range away.

Repro: 1.) Play as Ahri and Udyr 2.) With Bear form activated, run at Ahri and have Ahri charm you 3.) As soon as Charm ends, you auto attack her from a pretty long ranged auto attack distance

I don't know if it's a 100% repro, but that bug was pretty aggravating as it led to my death which could've been prevented.
