There's an NPC in Atlas park that offers missions for you to tour her facility and ultimately join her team. During the missions she (& the others of her team), repeatedly fails to follow you once you begin using the elevators. On the villain side, there are missions early on that team you up with a group of skulls, and Dario Stanzini. All of these follow much better, and do not get lost / confused / suffer pathing issues once you take elevators, etc. I would suggest using their control scripts as a template to correct the others' horrible pathing. I believe the Atlas Park NPC is Twinshot. Keep up the great work!
