Ever since 6 months there has been a Katarina bug, it happens really rarely, but when someone flashes right as you cast your E, you blink to where they flashed from, but don't do any damage to them, it's cost me a couple kills and I really hate it. Please fix!
EDIT: I added in a video link aswell so you can see it easier. https://www.youtube.com/watch?v=JIjdX4lNoaI&feature=youtu.be
