I managed to carry an awful team as support yorick and won the game.
The client lags me through the level up screen. Then through the Mission complete screen.
And the client then proceeds to kick me out of the lobby to brag about the "NEWER, BLUER ESSENCE". I don't get to talk to my team, review the match stats or anything.
And then I can't even open my level up capsule.
Get your popups under control, Riot. This is the basics of the basics. Stop interfering with the operation of your own client.
