Didn't receive ip from a game

For some reason I didn't gain any ip from one of my recent games (it didn't even show that I got any in the match history) . I don't really care all that much considering i only would have gotten around 200 ip with party rewards, I just thought it was kind of random and weird. Maybe it was because my internet crashed a couple minutes before we lost so it marked me as afk or something? Anyway just thought I would post, maybe it's happening to other people too.
