[GAMEPLAY] Braum can'cannot cross Anivia's wall with his E

Just came across a weird behaviour: • with Braum I use Stand Behind Me (E) to get to my ally. There is nothing between us that prevents the move. • straight after I press E, Anivia puts a wall between me and my ally • Instead of crossing (jumping over) that wall like I would do with any small terrain, I get stuck right before it and can't reach my ally. I did get the sound of the move ("CLANG") though.
