Client game laggs me out of game to update the inteface! wth

I was playing with nunu and then the game lagged, i though it would go away or i would have to restart the game etc. Yet i went to restart the game and when the client went up it said i had corrupted files and i had to repair them, firstly i hit the quit button because i wanted to finish the game and not be reported as leaver but it didnt leave me options, i had to restart the client and hit OK, now i was updating an interface taking ages while my game was running and i get reported... wth riot.

I think you should care more about buggs and game issues and not skins since it affects the GAME ENTIRELY.

Please fix this

PS.: I JUST GOT PUNISHED FOR LEAVING, RIOT LIFT THE PENALTY PLEASE... ITS NOT FAIR I GOT LAGGED OUT BECAUSE OF THIS STUPID INTERFACE UPDATING!
