Windwall Bug
Last month, a bug was discovered where projectiles will blatantly go through Yasuo windwall and hit him. In June, I had that bug happen but I thought it would have been patched by now. Throughout the course of many weeks, people have constantly posted videos about the Yasuo bug, including big streamers like Yassuo. However, the bug remains unpatched. In a single game, at least 3 Nami bubbles and a Nami ult went through my Yasuo windwall that was already activated. There was also another instance where Illaoi e went straight through my windwall. In a game where any little thing can snowball matches hard, a gamebreaking bug like Yasuo's windwall bug will inevitably ruin games. The game where I experienced this bug was still won, but only after two of our team's inhibs fell, which would not have happened if a Nami bubble didn't go straight through an already activated windwall, leading me straight into a stun lock with Caitlyn trap.
