Awakening of Evil

Well, I don't have a screenshot because I've already completed that mission, but it's below the Druids and not far from the Orc mines at the bottom. There's also a quest there to save the shipyard owner. I killed those wolves there. And there are no other wolves on the map. But after that, the quest for their pelts wasn't marked as completed.
Also, I have a question about the human spy in the Orc city. Who is it? I clicked on everyone I could, but I couldn't find them.

The wolves needed to complete the hunters' quest are located in the northern part of the map, well hidden under the trees, but they are easy to find if you highlight the objects on the map using Alt. For the quest with the shipyard owner, other packs of wolves are generated at the opposite end of the map; killing them does not count towards the hunters' quest.

The human spy is a shaman, standing next to the ore mine in the Orc city. She blends in with the surroundings a bit, so highlighting the objects also helps.
