I am in the spot where the dead npc with Remnant Power Armor should be (I verified exact location by watching youtube video guides) and the bodies are simply not there. I found a multiplas and tri beam laser rifle on the ground but no corpses. I fought and killed many regular Deathclaws and young Deathclaws, but did not see any Alpha male or Mother Deathclaws.
Has anyone else had this bug/glitch? Any known workaround or tips other than using the console to add the Remnant Power Armor? (I don't want to break the steam achievements yet as I have not finished the game).

My friend got this glitch, I haven't been there yet so I don't know

I have a feeling that they only become available at a certain level when I found the bodies I was already level 30, some people have said they only find those rifles.

I am level 22, so I don't think that it's a level issue, but I will look into this when I gain a few more levels.

i read in another thread where someone else had the same issue. when they reloaded the game and did it again it was there.

I ended up reverting to a save 2 level back and was able to get the armor. Very frustrating but I am glad I was at least able to get it. Thanks!
