[Client]Match history is definitely not working properly.

My match history : http://matchhistory.euw.leagueoflegends.com/fr/#match-history/EUW1/21867621 Out of my last 10 games, 4 are missing from the detailed match history : 1 2 3 4 (These are 4 dead links, don't bother clicking on all of them).

So.... that's about 50% of my games missing. That's quite bad. Riot pls ?
