New SR walls clipping blitz hooks

So on 2 occasions last game, Blitz hooked the enemy support passed two certain terrain parts, and instead of being pulled to Blitz, they bounced back and forth inside of the terrain before stopping on the opposite side of terrain from where blitz pulled them. First Blitz pulled them around the bend of bot lane, the second they were pulled over the short wall across from dragon pit. They were hit by the hook and pulled towards Blitz but they never made it to him. Anyone else experience this with knock backs or Blitz hooks?
