No Ip Given

So I just won a game and it disconnected me at the end for a reason I do not know. (My connection seemed to be okay). It didn't give me my first win of the day bonus Ip even though it said that I got it in the match history. I do not have any screenshots of before and after because I didn't know it was going to kick me from a game and not give me Ip. That's basically it, I don't know why that happened but I find it a little unfair.
