I have a bounty telling me to “Complete the Plaguemaw the Rotting (Normal) bounty in The Barrens. Party Includes: Murky” And i’ve done that 6 times now, even some on Heroic but it’s not getting completed… What the hell…
Who is the quest giver?
To complete those quests, your party has to include both the quest giver and whichever mercs the quest indicates.
So, you need to do the Normal Plaguemaw bounty with both the quest giver and Murky in your party.
I remember some of the tasks are bugged and won’t accept heroic mode. Try the party with the correct mercs in normal.
If this is just a daily quest save yourself the grief and just reroll it.
