champion select dc bug

i was in champ select when my wifi cut out so i dodged right away and when i got back on league i had a 5 minute dodge penalty, so i waited and then i played a game. after that game i looked at my match history and it said that i had played alistar (which was the champ that i chose when i dodged). Apparently the game went through and lost like 20ish lp. I don't know if it was just my computer, but something happened and im just trying to help. Thx!
