[GAMEPLAY] Aurelion Sol Comet of Legend [E] Bug

Yesterday, on the live server I was hit with Rengar [E] Bola strike (Not Empowered) , while flying using [E] Comet of Legend with Aurelion Sol. The [E] did not stop and I also found myself locked in flight and could not stop flying, and eventually flew into their fountain and died. This happened just once in one game.
