Overseer's Most Wanted

Overseer's Most Wanted is a side quest in the Fallout 4 add-on Vault-Tec Workshop.

Detailed walkthrough
This 'quest' is given through the Vault-Tec Population Management System, which allows, apart from other things, to track companions by marking them as quest objectives. Once a marker is activated for a companion, this quest will begin, ending once they're found. This is particularly helpful for tracking down companions 'misplaced' during travels. More than one marker can be active at a time.
