Hopefully this is the right place for this. I'm trying to make all the caravan folks like Lucky Harlith immortal especially as I'm playing with the Broken Steel DLC and can go above level 20. I looked in the wiki and saw the command: setessential 1. I tried this with Lucky. I typed "setessential 00063c08 1. (00063c08 is Lucky's ID and the 1 is for immortal.) Unfortunately all I get is an error message saying the Actor ID is wrong. I don't understand what I'm doing wrong. I clicked on Lucky and that is the ID number given. I don't want to play anymore until I make all the Caravans unkillable. I've already lost Crazy Wolfgang and have to find his ID to ressurect him. Stupid Giant Rad Scorpions everywhere and it will be worse once the Albinos show up.
To do this with the console I would recommend the following:
Open ConsoleType and Enter: prid Type and Enter: setessential 1
So, where you made the mistake was using the Ref ID on the Set Essential command for Lucky - you want his Base ID which is: 00063bf9
In regards to the rest of the Caravan, here is the info you need without having to search for it, provided in the format of Red ID / Base ID (or the order you will need them in)
Spoiler Crazy Wolfgang: 00063c07 / 00063bfa
Crow: 00063c05 / 00063bf8
Doc Hoff: 00063c06 / 00063bf7
Lucky Harith: 00063c08 / 00063bf9
Now, for the situation with Crazy Wolfgang, since he is dead and you need to bring him back to life, you will want to do the following:
Open ConsoleType and Enter: prid Type and Enter: DisableType and Enter: EnableType and Enter: KillType and Enter: ResurrectType and Enter: player.moveto
The move to part should be done somewhere on his designated path in game, like outside Megaton, so he can hopefully pick it back up.
