Had to reload, missed only 1-2 minutes, and was marked afk and rewarded nothing

So, on occasion I dont load into a game when reaching 100% load on everyone. I Alt+f4 to reload, and missed a wave or two. At the end of the game, despite playing the entire game never having one connection issue, I was marked AFK and wasn't eligible for rewards.

Please fix this. Only time it has happened, from the 20 times I've had to reload, but I would not like this to happen in a ranked match. (the game that it happened in was ARAM)
