Ok so there were a wandering villages with some lamas and i said to my self, "Ok i trade you later after I go explore my world first". So travel around the world and left the village the wandering trading was in. Once i was done traveling, I came back to the same villages I was in went back to the wandering Villager. I soon realize that the leads on those lamas was invisible and they move evertime the wandering villager move. I realize it was a "INVISIBLE LEAD".
