Selected matchmaking regions aren't saved when the client quits
Brief Description: The matchmaking region(s) highlighted green to join is not being remembered(at least on the UI) if you exit the client. The join solo pool button is still clickable though once the client is restarted, so something is selected?
How to Replicate: Click any matchmaking regions, then quit the client. Restart it and check the matchmaking pane again.
It should be working something like this UI mod I believe.
