So previously I have been able to add friends on other servers to my friends list and it showed online or offline etc. I did this way back when, and recently when I came back to the game as well. I have noticed in the last couple of months that the cross server doesn't seem to work. I can still add them, I get a successful message, and if I know that they are online, I can still send the tell, but the friends list does not show the online status. I never saw anything saying that this was going away, so I am guessing something got borked somewhere.
