[GAMEPLAY] Braum ult teleport

Was playing in ARAM and landed a snowball on the enemy Vel'Koz and used it to go in. Right after teleporting in I hit R and suddenly I get warped back to where I was along with my ult.

Don't know if this is a known bug with Braum or if this has something to do with the new summoner in the mode.
