Match History index page not showing Hexakill games

TL;DR: Match History index page not listing all games. Games are still processed, but not listed in index. Only Hexakill games affected.

All weekend (and today) I've had problems with the Match History web view not showing any entries for the past several days (which have all been Hexakill mode for me). The latest date in the index is October 25th (showing Sona in ARAM). For a brief time on Sunday, it was rendering all games up to the last few minutes, but today it is gone again.

Note that the games are still being processed, since if I'm in the Client, I can click Match History and then click a specific game, and it'll load that game's page. The only problem is the main index on the web site, so that if I go to the page for my account and want to show someone several of my latest games, the index will not list them since it's only up to October 25th right now.

Here's my URL: http://matchhistory.na.leagueoflegends.com/en/#match-history/NA1/202190547

It should show several days worth of Hexakill games (been spamming Soraka there all weekend), but it only shows my last ARAM on the 25th and none of my Hexakill games.

I also checked a friend's index, and I can see his ARAM games from last night, but not his Hexakill game that I watched him play last night.
