Caught a scripting yasuo.

In my current game im playing with a yasuo who managed to windwall everything. i mean aboslutely everything. I was in a bush (playing LB) that didnt have a ward in it. the enemy yasuo facechecked it and before he even saw me (i was still in the bush throwing out my E) he windwalled. There was no chance the bush was warded, he had to ward the bush to get vision and E me but he was able to know when i was going to hit him even though there were only milliseconds to do so. this persisted through the whole game.
