This started when I was in a game, was kicked (by em, not vegging) and tried to re-enter the game but couldn't. This was probably 2 days ago. All games, no matter the type or lobby, would end up with the same blank screen, as shown below.

Eventually, it would appear that the game had "loaded" because the tab's picture would show up, but nothing visibly changed other than that.

Aside from that original game, any attempt to "Join" a game never went through.
