Weird new Bug/Glitch

So i went to play a game just now and suddenly no animations and all models and minions stuck in their base with health bars going lower indicating that i was doing damage to them so i thought it was lag but my ping was normal and my messages to chat and pings we're instant, this happened multiple times in the game some happening after a while and lasting up to 30 seconds and some came after one another. Every Champion model just sliding in the air and no abilities to be seen in middle of the teamfight and no sounds expect the backround music. Fix please
