I modded a lot for Morrowind, and some for Oblivion, but this is the first time I have played with the Skyrim Creation Kit. I was able to find my way around in the new editor well enough, and I added the perk to Serana's list of perks. I have saved the mod correctly, and I have activated the mod correctly, but she does not have the perk. I have tried to disable/enable her with the console, and that does not help. I have tried RecycleActor, which also does not help.
If somebody could get me going in the right direction, it would be very much appreciated.
