2 issues I have seen possibly linked but one issue is that I cant recive party invites, if I get sent an invite I dont see it and I cant accept the invitation, the only way I ever know that I got sent one is that I see the timeout cancelled message. the other issue that I have is that I can't see other players in my area/party send chat messages in game and i'm pretty sure they can't see mine either.
