There was also an instance when my ping spiked unusually high and it brought me to the "Server has shutdown" screen even when I was still able to control and play the game. The server only "shutdown" on my side, and not anyone else connected. This only happen'd once.
Sometimes you get stuck in the "Verifying USGN" screen when joining servers, even when you close and attempt to reconnect.
Filter's only work in the "Server List" not favs or any other screens. Results in it still displaying ip's of dead server's and makes it look really messy.
