[Client BUG Health Bars not Visible}

I havent played in a few days, but i logged in joined a ranked game and my health bar was not visible, nor was any health bars at all so needless to say me playing mid 1v1 i had no idea how to keep track of what i could and could not do? By the time i asked my team in game they said it was a bug and to restart, so i did quickly as one possibly could, and by the time i joined i had lost my tower, and so early that we ended up losing the game. I have no idea why a bug exist in a ranked game, at least as one as big as that, That bug cost me the game, how can i count that loss as a loss is in fact it was not on my end. ??? Is there anything you guys can do considering the bug was ingame and was able to pass through unchecked. i want that loss expungedddd!!
