Gameplay bug

Okay, here's the thing... the last game i played there was an enemy Talon, i was playing as Rek'Sai. At one point i ganked bot and encountered Talon. As talon jumped behind Jinx with his E, i instantly knocked him...and he was knocked into the air for about 4-5 seconds, able to hit us but we couldn't see him or attack him. After 5 seconds he used his ultimate and fell back down. I don't know if there is a bug when he interacts with other knock-spells but at least try to fix this one. Thank you.
