Trying to do the weekly quest from Biergoth to get rep. Cannot complete quest again! Same thing happened last week. Two guild mates turned in just fine. I tried, and another guild member tried. Neither of us could turn in. The quest was for The Stonevault. I tried to log out, switch toons and neither worked.
Quick edit, I disabled all addons, and it worked. So I am now investigating all addons to see what one was causing the concern.
