Yorick post-game lobby bug
Post game damage on Yorick is really high (both dealt and taken.) If you look at the chart he took more damage than their entire team dealt combined. I don't think that this is something that affected gameplay but it definitely makes it hard to tell what the actual statistics were.
I queued with 3 others for this game (including the Yorick) and everybody in the room said they saw the same thing when we asked. Not sure if that helps with targeting the source of the problem.
