Issue #24488: Vault Tec Rep. can die on his way to Sanctuary
You can find him in Goodneighboor and can convince him to travel to Sanctuary. Once in Sanctuary, you can recruit him as a settler.
Problem is, he can die on his way to Sanctuary.
Just happened in my game, waited 48 hours, no sign of him.
So I used the console
and he spawned dead at my feet
used recycleactor and all went well, but still
