Hello,
There is a problem with tracks we can't see. We know there are tracks (with the absence of the message "You find nothing") but they don't appear on the floor, sometime they appear misshaped atop our character's body at random.
Moreover, it's very frustrating to follow horse's tracks, when you finally find some, and then lose them because there is a bunny or a chicken... I think we should be able to track small, medium and big animals, it's more realistic, a track of cow is deeper than the track of chicken... (Not couting the shape of it)
