Missions won't complete or accept achievements

Please don't tell me** "Have you google it? Idiot."**, because yes i have already google it. So as i was completeing my missions such as get first blood, win an ARURF match, win 3 PvP games, ect... So as i was in an ARURF match, i got a first blood, and (barely) won the match. I was like okay that's 2 off the list, that was easy and as soon as i check my quests, nothing happened. It just didn't accept anything i've done, so i went a few other matches, maybe it was just one time. But no, i went several matches in draft, twisted, aram, and summoner's rift, it didn't accept anything i've done, the first blood, the PvP wins, the ARURF win, nothing, just nothing.

Because i'm writing this late night i might not be able to respond today to you answear but i'll try to stay awake.

Thank you for your answears

By the way just noticed the notificaion about this bug, but i'm curious about your answears
