I get the "search body" ability just fine. I have just tried it briefly in Candlekeep on the sleeping person upstairs in the inn.
But when I use it on him, he just... glides off? His sleeping body just slides away and disappears. Nothing else happens. This seems very buggy to me and a bit dangerous to try to use in certain situations? Like if a person has quest items on him and he just slides away
Anyway does anyone know anything about this? Can I repair the mod in Near Infinity or something?
