Spawning npc's in single player

[ArcticWolf]

What you need to do is this:

Depending on how many AI you plan to use in the map, take a LARGE group of them (you'll have to give all a seperate group number) and place them far out on the map away from all the action - make them Deaf/Blind/Guarding so that they don't move from where they are. Then set up your events so that you can teleport them to the proper teleport marker as needed, and yes it can be done.
