I basically followed the instructions in this video https://www.youtube.com/watch?v=AlepT3rQ8LI, instead of making the id "NewFollower" I made the id "CustomFollower" and instead of putting them in the Dragonbridge tavern I put them in Dead Man's Drink in Falkreath, I save the plugin in my data folder and I go to the Dead Man's Drink in game, but I don't see the new NPC anywhere, so I look for it in the console by typing "help customfollower" I get nothing in the console, it's as if it was never even installed, but I know it is, please help

1) Did you remember to activate the .esp in your Launcher?

2) Did you give them a name? If memory serves, 'Help' requires a Name, not an Editor ID. So try searching for their Name, instead.

3) Did you give them any packages? If you duplicated an existing NPC, it's possible that perhaps they got some package that sends them walk about somewhere else...
