This bug is a bit annoying because it is good to know how the teams were balanced after the game.
In a game that I lose, what USED to happen is once the game was over the complete stats for the game would be displayed as well as the leagues of all the players.
NOW, it just freezes with the stats of the game at the point when i left and does not show the leagues of the players. It just remains “in progress” even thought it is in my match history as a loss. The leagues are not displayed when I open up the stats of the game through my match history though.
