Orianna ulti bug

Orianna ulti isnt properly knocking players, for example hecarim was with his e charged, and was going in my direction , i knocked him up, and him being far away from me i still got knocked up by his "e" ability. Other example on hecarim also, he was chargin with e and with the ulti animation being on him and with the ball on top of him, he dindt get damaged or knocked up by it.
