Contextualization:

Since I started doing the mage glorious campaign questline I am following this guide http://www.wowhead.com/achievement=10994/a-glorious-campaign#comments:id=2462971 which has been several times referred on this forum as a correct guide for this questline. Moreover, I am re-checking every single sub-quest’s status in this questline using a command that tells me which quests I have already completed and which I haven’t. Code:
/run local questID =XXXXX; isComplete=IsQuestFlaggedCompleted(questID); if (isComplete == true) then print('Quest' , questID, 'is completed. ') else print('Quest' , questID, 'is NOT completed. Check again') end;
