Match History Bug

I had the same thing happen to me and a couple friends. One of our matches is not showing up in match history, yet games we played after are showing up. I've never had this happen before. I've had games that are slow to appear, but not an entire missing match. Just to clarify, we played a summoner's rift game, it doesn't show up, then we played an ARAM and another summoners rift and those 2 do show up.

Same here, it has been happening since Thursday.
