I am in chapter 4 and have not paid much attention to the challenges. I recently find out to get one of the legendary animals I need to be at level nine in the hunting challenge. I need to track 10 unknown animals to complete level 3. I have hunted most of the large animals up to this point. I managed to get the first one, a whitetail deer, an animal I have hunted a lot. I have tried other animals I have hunted, but it will not register for the challenge. Do these have to be animals I have not seen before? Is there size requirement as I have been told that you cannot track birds and tracking small animals like foxes and raccoons do not work either. Is this because they are already in the compendium? Am I hosed on completing this level at this point? Thanks
