If there are npcs then they are located somewhere. Usually loaded in a .Json or .cfg file. I haven't seen a PI source that had a class called autospawn so if that is what you are looking up that alone could be the problem. Try searching "spawn" "spawn_config" or simply look in your json or cfg file/folders for something similar. Or look up the coordinates of a npc that isn't moving. It is most likely there just keep searching.
