I'm not sure if this is new or I've just forgotten in the years since I played Morrowind or Oblivion. I don't think it's a mod, but the AI (guards or npcs) track your movements while your sneaking, even if your invisible/chameleon. The Sneak/Awareness Icon is still grayed out, but there head still tracks. This even if your behind them, sneaking and invisible. It's extremely annoying and breaks the atmosphere, as a Stealth player (can't imagine it's just me). Is there anyway to stop this behavior?
