For expert hunter while hidden, shoot then move to different spot while sneaking and besure to stay in the dark areas. Its also based on how skilled you are in sneak.
So for the evil or bad players, bewarned, the AIs will cheat and track you down no matter how good are you at sneaking around when entering, exit, or sneaking around in the woods. Because they have it set as spawn points in certain locations.
