Cannot see Yasuo wind wall particals.

I was playing Vayne dueling a yasuo, yasuo E's me and wind wall at the same time. I then stand in the same place to auto Yasuo 3 times with him taking no damage, obviously. Sounds pretty stupid but the problem is i did not see the particles of the wind wall at all. My teammates said they didn't see a wall either. I then checked the replay on replay.gg and that is how i saw that there was a wind wall. This cost me the game as it was at the 43ish minute mark and they end the game on my death. This is very frustrating because there was absolutely no wall when i was in game. The link will be the replay on replay.gg . If anyone can explain why it would've happened. (eg. wind wall was casted into the wall, etc.)
