I was doing a quest, The First Step. It's one of the first quest you get in the game for people who may not know. Anyway I was in the assemble factory thing and he was with me but then when I finished in there and left he was gone.... Now before people start telling me things I have already tried, I've tried just about everything to get him back besides starting a new game and I really don't wanna do that but things that I have tried would be building dog houses in most of my settlements to see if that would help and built bells and all of my settlements and tried ringing them to see if he would show, and he was a no show :-/ and I went to the rocket gas station place and never showed back up there either if anyone has any other solutions let me know. I tried contacting Bethesda and they sent me a e-mail basically saying just use the forum...
