I’ve done Wailing Caverns, BlackFathomDeeps and i’ve done Shadowfang Keep twice. I’m missing the achievements for these dungeons on my worgen in Pyrewood Village. I tried to get a GM to answer and so far I have an auto response not a solution.
I am in similar situation with loremaster achievements. In particular Kalimdor ones being tricky. Essentially kalimdor page shows i have all the individual achievements for kalimdor loremaster,yet i dont have it because some of them remain gray under the achievement. I just submitted bug report and hope for the best that they eventually get around fixing it.
