I'm playing Fallout 4 on Xbox, and there is this glitch that I've found to be quite common, but no one knows how to fix it. It's concerning the Merchants who can come to your settlement and are level 4 in selling stuff. I can find them on the road and trade with them, however, once I actually meet the requirements to let them join me, they either don't show up in random encounters or they don't have the dialogue option to come with me. I tried for days to make The Scribe or Smiling Larry spawn, but they wouldn't. And Doc Weathers won't come with me because there is no option to ask him to.
