"Casting a Line" mission broke due to Jake wandering into Sanctuary

[Xavius]

In the mission Casting a Line, Jake had (for reasons unknown to me) decided to come to Sanctuary while I was building stuff. Dialogue started and the mission began; however, because I was in sanctuary, Old Paul coming over to mention the raiders simply won't progress, and Jake has wandered off to who knows where. How do I get them where they need to be for the problem to be fixed? Does anyone know the move to player command I'd need to do? Is there a different, easier solution?

Update: I managed to push Old Paul out of the Sanctuary border manually, and he promptly booked it to Concord. Jake was still nowhere to be found, but he did his dialogue parts from inside a bush at an unknown location, so I was able to continue the quest just fine. Still something to keep in mind: Do Not Talk To Jake in the wrong places.
