So I was scrapping some junk, and Nick Valentine walked by in front of me. I didn't pay attention to him and continued scrapping. I scrapped a pile, then turned to another. I was trying to scrap all the junk ASAP because I wanted to go back to looting the wilderness. Nick was standing in front of the pile, and before I realized he was there, I turned, pressed Square to scrap, and pressed X to confirm. Nick was gone. I had quickly looked at what materials I would get for scrapping what I thought was something in the pile, and it said '5 circuitry, 10 cloth, 15 steel' (Nick's 'materials'?) I reverted to an older save and he was there.
So scrapping companions is somehow possible? I would have never thought this was real. I even tried doing it a few more times, but no success. Is this a bug or some sort of hidden feature? I'm weirded out by this. I'm on the PS4, too, so no mods were on.
