My match history hasn't updated since the last game I played yesterday. Since then, I've played a few aram games already and I am still playing. I restarted client and nothing. My match history still hasn't updated from last night.
UPDATE: As of 3:30PM EST my match history has updated
BACONARMADA3 votesMy match history is showing someone else's games. I know this because I don't own or play 
but there are a ton of games from him. I also click to see the match statistics and it shows another username over the .

Ànri2 votesyea same thing is happening with me i went to get some runes and it said i could not buy and cause my ip went down and then i look at match history and the last 3 ranked games i played were not there
Baby Peach1 votesI have games that aren't mine. Everything can remain the same and I even relogged, but the Match History is completely glitched. It's saying I'm someone that doesn't even exist; then after relogging, that I was someone who (looking the person up) was Level 17 playing ranked in match history. But a friend looking at my account from his client has my correct history.
Some people have matching match histories and when you recheck, it changes.
Some of them don't even have names on their histories, as if they were bots.
NotLikeThis.
Edit: My Russian Account has a Match History on someone in NA. Amazing =w=
