Just because every single one of my alts has run into this and I've come home to find it stuck in one spot and a certain quest not turned in....
A Mammoth Undertaking - Quest - World of Warcraft
Quest Name: A Mammoth Undertaking
Profile: 68-80 Horde (not sure if the same happens on Ally)
Problem: The path it takes to return the mammoth takes it through a pack of dragons instead of looping left or right around them. Mammoth dies and bot sits in front of quest giver and can't turn in.
My solution by hand: Taking the mammoths along the left side, and maybe running into one mammoth that attacks (I usually ignore the mob, run straight to quest giver, turn in, and then kill the mammoth easily).
I've only got one more alt that needs to do this quest but maybe it'll help others.
