Have you checked your quest log to see if the game recognizes your quest? Are they all green?
Please be sure that you killed all these 5.
-Hjalmar
-Hallorn
-Yup'ik
-Viper
-Jagon
Those are the First group of villans from Broken Valley. Rewmac is in the Fjords.
The problem was I had the items because of going everywhere on the map thanks to other quests. I knew about the hunting because my friend told me I looked up the names, but I forgot to take the quest from the board

I took them all and finished it.
