DC Bug Splat

I was in a ranked match just now winning then all of a sudden everyone started experiencing heavy lag including me , then out of the blue i dc'd from the match an it said error has occured and bug splat, so i proceeded to restart the game and kept trying to login for about 10-15mins but kept getting stupid error. Now that im finally logged in match history shows my team won the match but i got leaver status and lost 20lp because of your garbage bug riot.....
