Karma invincible BUG

So i played a game as Pantheon against a Karma and ran into this funny bug… Karma had 86 armor, Pantheon Q deals 455 AD damage + W deals 45(?) AP + E hit a few times and Karma was still at full HP{{sticker:sg-lux-2}} I think Rito accidentially made Karma invincible in one of the latest Patches... Must be some coding issues, because i can't imagine thats on purpose, is it?
