[GAMEPLAY] Aurelion Sol's passiv

Hi everyone As a main Aurelion Sol I often play him in ranked game, and already two times it happened, I didn't had any lags at all and Aurelion Sol's passiv wasn't hitting at the right moment. Damages were made, but like...1/2 seconds after the animation was set on minions or enemy champ. I couldn't farm very good and obviously in fights I was a bit useless after Q and ultimate were cast. When I look at the replay of the game, everything is fine. I don't know if I am the only one but can Riot please investigate on that ?
