Joining from a Steam invite now works when the game is closed. Accepting an invite (or clicking "Join Game") used to launch the game and then drop you at the main menu instead of your friend's lobby. You now skip the intro and land straight in the lobby, even on your very first launch.
Accepting an invite mid-match now takes you to your friend's lobby instead of silently doing nothing
Friends are no longer timed out while still connecting. Slower connections through Steam get more time

Fixed lag spikes and ruons with any packet loss.
