Hi guys sorry if this has been asked before but I couldn't find it in my search.

I have some NPCs I don't want the player to be able to talk to and would like them to use the "Nothing to see here, move along" dialogue some Brotherhood of Steel NPCs use when the player tries to activate a conversation. In other words I want them to simply say that and end the conversation, not allowing the player to ask any questions or use the "friend" option from Sharing and Caring Companions mod.

How would I go about doing this? I did it by accident with one NPC and for the life of me can't figure out what I did different.....

Thanks
