I was messing around and killing some guards down the roads, but sometimes the AIs cheat when you are completely hidden from them. A bounty hunter, messangers, or npc calling for help will head directly to you while you are hidden in the shadows. So i find that annoying, would like that to be fixed someday. As the real thing or being realistic, there is no way that npcs would noticed i was there in the first place.

You will noticed if you fired a arrow from point A to B, if you manage to hit them, they will charge directly to point A automatically. 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.

You can move virtually undetected with a skill level of 70 and only 1/5 in the perks. Firing an arrow at a rock will cause the enemy to go straight to the point of impact. This can be done to actually draw enemies out into killing view.

However, in the event of the Bounty Hunters.... They will always head straight to the player character.
