[GAMEPLAY] DJ Sona

Every time i play vs DJ sona i have ALOT of issues with LoL. First off the game might freeze at a random moment, i can cast spells move my character(I can tell my the sound ) but the image is froze. So after that i close the game and reload the map structure is different visually, monsters/champions become invisible and i can only see their HP bar floating on emptiness. This only happens while i play with a DJ sona on my team or on their team, and i seem to be the only one having these problems.
