Yasuo Windwall Doesn't block TF Gold Cards(Gameplay)

In a ranked game today I was playing as Yasuo. But whenever I threw out a windwall to block a Twisted Fate Gold Card, the animation of the card would disappear but I would still get stunned and take damage. It happened several times, and even the Twisted Fate on the other team was like "wtf, how are my cards hitting you?" Please fix the problem, I lost the game today because of it.
