game breaking bug that i cant describe in title

ok so I go into a game everything is normal until minions spawn once the minions attack each other

my ms freezes at 200 and everything stops attacking, casting etc.

however damage still applies and once something dies its hp bar disappears and it stops moving and the model stays in its place

bottom line is I can't move or attack neither can anyone on my screen and I still take damage

apparently I'm not the only one suffering from it a few of my friends in league have it too

haven't played league in 4 days now plz help

re-installing did nothing
