So this is what happened: I was on my way to the Dead Money DLC and when I get to the entrance I decide to send my companion, Boone, back to the Lucky 38. So I go and finish Dead Money, but when I get back he is nowhere to be found. I have checked Novac, The casino, I tried the Vault 22 trick, going to the companion dismissal terminal I even spent an hour searching the area around the Abandoned BoS bunker, found nothing. I am playing on Hard so I know he can't die and I am just befuddled by this. I have all the latest patches and have had almost no problems with bugs before this. Can anybody help?
