So, I think you should be able to tell the difference, the issue I think we have is that we have auto spawning critters, and they walk from place a to place b and then unspawn. I don't want people following random tracks to nowhere as that is frustrating. Might need to refactor this system so it is more usable– maybe if the NPC despawns it removes their tracks or something, that way if you find something you know it is legit and worth following.
