This is becoming really really frustrating. I've been through huge amount of problems with LoL sites. Now it's this:
#404 - Match not found
**The requested match was not found. **
Any of the last matches I've been through, the match statistic were no longer available. The older matches are still working (eg. nothing dissapeared, but now new data are available).
Yup, same here. Can't see any of my own nor my friends' recent online match histories for the past day or so.
Been happening to me for a while now 
+1
Happened to me today on my 3rd and final match of my day. It was one of the most intense ranks I think i have ever had (Stole drag and baron) and I go to look at stats and i get this. Also, i go to look at my mmr on na.op.gg and it doesn't show the match there even though i refreshed it only shows the match i played before. Rito Please
