This quest certainly taxed the socially challenged of us. Finding 4+ people to work with and doing things in the correct order was fun if a little frustrating until the team finally "got" what to do. I even found myself later going back to help another group achieve the quest.
However the "Try again" button on the quest is awkward to set. And then you have to select the peat and dig without getting caught up with the menu for one of the other players.. It would be nice if the peat menu had a "start quest" button right there.
