By the door in Webbers shop there now stands a Butcher that replaced a Stonebuilder that was standing there.
This Stonebuilder was part of the ambient dialogue though (With the human model next to him). Which would occur every so often (In the same vein as the npcs in the House of Knowledge).
But the Butcher does not have the same dialogue the Stonebuilder once had. Making it so the human model is doing half of a conversation.
Sounds about right. Butcher would just stare at them.
Except the Model half way replies to the now missing Stonebuilder; "Really, you think that?"
Which looks rather odd without the other half of the dialogue.
