Appreciate the reply!

Was it necessary to add any special code, such that a follower "knew" to activate and follow the PC?
Thanks!

Nope. Nothing at all...
May be the way the followers work, as some people have stated that they COC'd to my cell and their followers followed them in, providing me screenshots as well. I'm honestly not too sure. And Honestly I haven't even tested it myself with the lack of time. I had specifically stated on the mod you weren't allowed to bring followers in, and hours later I was messaged by numerous people saying there's a bug and their companions were following them in, others saying the NavMesh was messed up (Of course... Didn't make it lol)
So from what Ive been told, they follow them in fine. You have their experiences, but I honestly cant say for myself.
All I can say is try it. Ill tell you exactly what I did as I am not home to test all of this:
One thing that may make a difference though, is I used that obelisk looking thing (not home to give you the actual activator) which actually acted as a door, which may be the reason it worked. I had scripted it to teleport the Activator to an X marker via a script - I did not link via references. I would like to think that this is what is making it work.
Hope some of this helps.
