Azir Ultimate bug (Gameplay)

While playing on the rift I went to gank midlane from the top lane and Azir ult'ed me into a wall and it held me there for the entirety of his ult and my champion could not move at all and kept bouncing in and out of the wall unable to move or use abilities. I don't face a lot of Azir's, but this happened twice to me and once to my friend. I could not flash out from it either.
