Everything stops working...

12.2.2018 was a nice day when everything is fine and i'm enjoying this game called League of Legends (not sure if you've heard of it), but then... 13.2.2018 everything went to shit. I start up League go and make myself a cup of coffee and start queuing for a draft pick game with my friend, then we find a game, i got chosen as the Bottom and i decided that i would play as Sivir. Then after about 4-7 mins or so, minions are not dying. After a couple of seconds i can see 10 enemy minions and about 10 ally minions that are on 0 hp and still shooting at each other and when i try to attack nothing is happening, can't even use my abilities. 10 seconds later i'm losing health really fast and now i'm myself on 0 hp and not dead. After about 5 seconds everything that was supposed to happen 20 seconds ago happens in 2 seconds all at once... so now i'm dead, the minions are dead and some of my teammates also died at the same time. The next game i was put as jungle and wanted to play kindred. When i have cleared the blue side in the start i'm on my way to the red side, and when i arrive there.. red doesn't exist and then he just appears like that. This happened a couple of times and it took me about 2 mins to realize that everything is invisible and i can't see when i attack, use abilities or even die, and the same goes for minions and monster, can't see when they attack me or they are just invisible.

Long story short= can't see attacks/abilities and can't see enemies, minions or monsters if they are in the shadows/mist (what ever you want to call it) when this bug happens and also i can't see if anything (champions, minions, monsters) dies they just go to 0 hp and stay there. Now this bug is not continuous, it's happens at random points and usually last about 5-40 seconds then everything goes back to normal.
