Guild Wars 2

For the last 3 or 4 instances for the personal story my friend has been unable to join my story line. I am able to join his, but for some reason he can’t join mine. W are partied up and, we make sure we both are in the same server/etc.. so that I can turn my camera and physically see his character, when i go into the instance it doesn’t offer the instance to him, i just go in alone. I am playing a sylvary ranger and he is playing a human elementalist. (not that it matters but both are male characters). I was alerted that this might be a bug, any ideas if this is a bug and how to fix it? Am I totally out of luck?

Thanks.
