Most of the pieces are dropping so far, but a "Collector's Canine" (from Drolvargs in Firiona Vie) hasn't yet. Myself and others have encountered this problem.
Lockjaw is the server. I am hunting in the Firiona Vie zone, and I only recognize one type of Drolvarg. I don't see a distinction between old vs new models.
I saw Collector's Canines on drolvargs in Firiona Vie on the Ragefire server. Didn't see Collector's Canines on drolvargs in Firiona Vie on the Lockjaw server. Looked through the data and didn't see a reason why they wouldn't drop. Reppoped Firiona Vie on Lockjaw and now they are dropping the Collector's Canine items.
Super, thanks. p.s. I had entered the wrong server name in the title to the thread, and didn't realize it until last night.
