It happens almost daily when I try to join a person. I try to join a party so I can jump into a main server but then it says the player cannot be found even though I type his or her account name. Don’t know what triggers it or fixes it.
Another problem is sometimes when you right click a name you can’t invite or join that person because there is nothing to click on. Then the first problem also happens if you manage to be able to click on something.
