Pantheon Passive / Yasuo Wind Wall Glitch

So I was playing a normal game. I was matched up with a Yasuo as a Pantheon in the top lane. While in lane, I soon discovered that Yas Q was able to go through my passive, which is very odd because it never happened before. It's really bugging me since Yasuo was able to get a lot of damage that should be blocked. His AA still got blocked, so that's good. Later on in the lane, my Q go straight through his Wind Wall, which, again is extremely odd. I figured this is a bug, so as soon as the game is done, I reported this immediately. Hoping this problem will be fixed in the next patch, and the game should be return to the way it was.
