Glitch causing people to afk

It seems that every time someone takes an abnormally long time to load the game, once that game starts he's afk and theres a remake. This happened to me once, it took so long on the loading screen before the game and suddenly the client opened up and said that my team remade.

I see this happening all the time; the game starts with one player still at 60%, and lo behold, that player was "afk" and there's a remake.

I'm so tired of wasting so much time with these remakes and at this point it's clear that there's some glitch that's disconnecting people, and they aren't really afk.
