[GAMEPLAY] Sion unable to ult through allied Base Gate

On Sion, when ulting, he is unable to travel through the Base Gate. The behavior is similar as if he had crashed into a normal wall.

1. Move Next To Base Gate
   

2. Attempt to Ult (R) through Base Gate
   

3. Crash into Gate as if it were still a wall.
   

I've tried this a few times and this has happened each time. It occurs on both blue and red side, as well as both gates. It occurs going into the gate and going into the base.
