I had the misfortune of experiencing one of the craziest bugs I’ve seen since release. While rounding my enemy’s lizard camp on SR, I found that that lizard was down but the little minions were attacking something. I couldn’t see any hero, though, so I started to kill them so I would know when the camp respawned.

Suddenly, I heard Udyr’s Bear Stance and I got stunned, though I couldn’t see him. I thought it was lag, but I had full control of my character. Udyr…was invisible. I’m talking completely invisible, not even towers could see him. It was a terrible bug to experience, especially as an opponent. He could run around during teamfights and attack us and there was almost nothing we could do. I did manage to kill him once by attack moving near his location. Worst of all, our team was stomping theirs, but with such a strong hero permanently invisible, there was little we could do.

At one point my teammate started furiously pinging the enemy healing pad. There was Udyr, running and changing stances in place, just as he surely would have been on the field were this not massively glitched. This is horribly gamebreaking, and unfortunately Riot says it has been difficult to address because it’s hard to reproduce. Apparently it can happen with multiple champions, though my forum searches seem to find more instances of it happening with Udyr than anyone else.
