At some point during the game, every spell Aurelion Sol casts freezes my game for like 10 seconds

And then I have to restart :/ really sucks. He got a couple bullshit kills on me because of that. I was playing Infernal Akali against him mid at the time and whenever he was on my screen and cast W or E my screen would freeze for 10 seconds, or my game would straight up cast. Had to restart multiple times that game.
