Says who?
They both have no clan.
Adding clan everywhere because "we must" without retail info, is not going to happen.
They both have no clan? Its literally in your files. Theyr clan tags are all set to "ALL". You can even put Treant NPC next to a zombie. Hit the zombie and the NPC will aggro you.
Im not adding the clan tag everywhere, im just modifying the existing tags so that mobs and NPC wont behave like this.
Anyway Im not here to argue, do as you please with this information.
