I was playing on the NA server last night and in a party with a couple of my friends who were also playing on the NA server. We decided to meet up and do some trading but when we went to the Othrenis wayshrine to meet up the two of them could see each other but they could not see me and I could not see them. They also did not show up in my "in game" friends list and I did not show up in theirs. I tried rebooting the game and re-logging but that did not change anything.
Has anyone else experienced this?
Are there different "instances" of the NA server? Is this a known issue that they are working on?
