got a bearer thrall
had it on follow then told it to stop
it now randomly moves around usually in my direction.
dont know if this happens with other thralls yet. only have one.
bearers only have 5 slots making them no different than any other thrall.
also it also is in permanent combat stance.
bearers should also not engage in combat but should avoid it. thralls need an aggression setting. Ie: passive, aggressive, defensive.
