Wind Wall stops Unstoppable Onslaught

{quoted}

wind "wall" sion stops when he hits an enemy champion or wall or has reached the max range of unstoppable onslought

But Wind Wall is not a terrain skill (like Anivia's Crystalize or Jarvan's Cataclism) and should not be stopped like he would not be stopped by Karthus' wall. I think I've read in patch notes this bug is corrcted, you should check again.
