The quest Brunt: Liquidate the Icy dire wolves says to collect 10 Icy dire Wolf Pelts from the Icy Dire Wolves. I killed about 30 and no pelts as loot. I got my tanning blade and killed about 10 more and was able to harvest 1 Icy Dire Wolf Hide per wolf but no Icy dire Pelts.
The quest was bugged. Fixing.
