Jhin Ult Bug

Not really sure if I'm the only one getting this but sometimes ( I'd say maybe 1 in 5 times for me today ) after activating Jhin's ult, champions who are at a Medium/Long distance to Jhin, become impossible to hit as, for example, the enemy Soraka would be showing to be moving down, only to then slide around and be far over to the left (think of Call of Duty lag movements if that makes any sense) making it somewhat hard to aim shots at all because of the unpredictable movement of a champion. During the games this happened I had no Ping/Frame Issues and again it was only to champions who were at a Medium to Long Distance from Jhin.
