I accepted Disturbance Detected Black Temple, went through the entire raid with a group and killed Illidan. However, he did not drop the quest item for me to complete and turn in the quest. I thought maybe a bug and got into another group later to kill him and again, nothing. I cannot complete this quest this week for timewalking. Is there anything I can do to work around it?
You can try putting in a ticket but no guarantee they will help you.
