NPCs and Creatures talk to and headtrack a player character with a 75% chameleon effect or more
In OpenMW if your character has a 75% or more chameleon effect applied; NPCs and creatures can talk to and headtrack your character, they also turn their direction to your character too.
In Vanilla they don't do that, unless you have 74% or less chameleon effect applied on your character.
This was tested without sneaking, and happens with both 0.46 and 0.47.
