I have just created a new toon and I am levelling a Troll Hunter on Death Wing. I am doing quests that I always do when levelling a toon but I seem to be having real problems in the barrens. I am killing mobs that I need for quests but when I kill them they are not adding to my quest as having being killed. When killing Baron Longshore his head is not in the loot. When killing Isha Awak the heart is not in the loot. These quests normally work I have no idea what is wrong, I have tried reloading I have tried logging out and back in and I have tried deleting my cache but none of this has made a difference.
