So I've been trying to add the Trainer function to some of my followers in this mod I made, but I can't to get it to work. I copied how it looked for some of the NPCs that are Trainers (like Collete), adding the in-game Trainer Script and adding them to the faction, but the followers don't have the Training dialogue in-game. Is there something I'm missing?

I'm having a similar issue trying to get the brawling quest to work as a hiring prerequisite. I copied the way it looks for Uthgard, adding the Favor017 faction and quest to the follower, but it doesn't let them brawl - they still just let you take them with you. What exactly needs to be done here?

Also, I want to make a merchant follower, but I don't know exactly how to make a merchant, and I'm wondering if its even possible to have a combo merchant/follower?

For the trainer question, did you set their classes as well? Also, most (maybe all) of the training dialogue is NPC specific.
