I have done all 3 of craglorn trials on normal & both Hel Ra citadel & Aetherean archives on veteran in last 3 weeks & still didn't get that achievement.
any idea what's the problem or how to get it?
None of the crags have been the weeklies here the past weeks (XB EU). Its only if the trial is the weekly one. (see in achievements-> leaderboard weekly is shown at the top)
