In a nutshell, it's the In The Dark quest line for the Brotherhood of Steel, specifically the paladin in the centaur pit that has the hvmissiondisc03 for the lost patrols. One of the two paladin corpses spawn, but the one I need, hvpaladindead06 never spawns regardless of how often I reload a save or go from cell to cell. Usually the other paladin spawns, but never the one I need [if there is indeed two paladins, the note on the fallout wiki insinuates there is].

Ideally, I'd like to make a mod so I can pick up the note from a container or have the paladin corpse spawn somewhere else, like goodsprings, I figure I could probably add the note, but I don't want to disable the acquisition of achievements. The note's base id is 0015a7b9 if that helps.

Edit: Alright, if this helps, the paladin's ID is 15a7b8.

Edit2: Alright, I feel silly, but pleased with myself. I was messing around and look at get guides, then came across this tutorial thing on youtube http://www.youtube.com/watch?v=Y2xskfNS8HE&fmt=22. I did as it said, and managed to open the cell in doc mitchel's place, then messed around until I figured out how to drop in a container like the sarsaparilla crate and then dropped in the note. Saved it, loaded it up, crate was there, so was the note, but it didn't update my quest. I then went back to the editor, found the actual dead paladin I had to find and dragged him to the floor, saved, refired up the game and bam, there he was, and this time, it updated my quest. Actually, I just went to the Brotherhood Elder and it worked, man, this is awesome. I know no body responded, but due to all the resources we have for this game at our disposition, it fixed me up, thanks, guy.
