Party Host getting kicked to login page because round already finished.

[olendvcook]

If a player joins a round before the host instance does (like if he's in queue it will requeue immediately while the host session waits 5 seconds to auto queue) and then the 1 player leaves the game, we will close the game for having no players. After the host session moves on to the next round they get an alert that the round is over and are kicked to the login screen.
