  • The quest can be failed if the player character moves too far away from Austin during the visit. Additionally, the quest will also fail while conversing with NPCs while on route to different locations in the Vault.
  • If the quest is started late at night, it is possible to become "stuck", as Austin will go to bed without the tour being completed. To avoid failing the quest, one may need to wait for him to wake up again.
