I cannot get the Clan XP Milestone to activate on my 2nd character. It's available on my first character. Both characters are able to contribute xp to the individual 5000 per week goal but the milestone does not appear on my 2nd. They are lvl 20/278 and I have completed the story. Is there a list of things that have to be completed before the Clan XP Milestone will activate? I can't seem to find an answer to this question anywhere.
