Ornn E not working properly

So I was gonna give red buff to Lucian. I did the standard q, auto, w, auto, then was gonna e the buff, however when I targeted my E towards the magma pillar from my Q, Ornn dashed up and through the red buff wall. He shouldn't have gone in that direction, and if I did click there he should have stopped at the wall instead of dashed through it.

You can see that the knockup radius showed up on the wrong side of the wall as well, so it wasn't just a case of my model glitching through after the dash, the game actually registered Ornn as having hit the wall from OUTSIDE the red buff pit.

I've had this bug happen 2 or 3 times, but this is the first one I decided to actually clip and report.
