Frigidazzi's goblin servant wanders the streets all willy-nilly. Rotoluncia's servant steps outside the building for a smoke. All kinds of strange behavior happens with NPCs set to Wander (or Loiter, or whatever the particular schedule is... I didn't check). In the original, they tend to stay to the specified schedule coordinates, but in Exult they wander freely.
I'm not sure if that is stil valid.
Loiter stays in a smaller general area, where Wander has several times the roaming area.
Seems this is a real issue where the Wander area is determined by the view area. Using the Point scaler, the distance of Wandering is higher on 3x than 4x.
