I have Interesting NPCs installed but have not been able to find a follower mod that works with it. I've been using Amazing Follower Tweaks (AFT) for a while, but could never add more than one of the interesting NPCs as a follower at one time. I'm able to use Lydia and one Interesting NPC at the same time, but any more interesting NPCs I try to recruit will not come with me because I already have a follower. I tried dismissing all followers, removing AFT, and then re-recruiting, which worked for the iNPC, but Lydia didn't even have the "follow me" dialogue option. Next, I tried Extensible Follower Framework (EFF), but this also didn't help me add more iNPCs, so I tried Simple Multiple Followers (SMF) next, to no avail. Finally I gave up and told myself I could live with having just one follower, and removed all the follower mods. Then I went to Volkihar Castle to meet with Serana to go to the courtyard, and she was in her underwear. I traded her some clothes, which she put on, but as soon as we got into the courtyard, she took her clothes back off and would not equip anything I gave to her. I'm afraid all my messing with follower mods totally screwed up something in my game and now I'm at least looking for a way to reset all of this. Any help?

tl;dr: I've tried AFT, EFF, and SMF to work with Interesting NPCs, but none of them worked, and I'm afraid I've messed up something fundamental in my game.
