Another NPC named Atticus is found in the game's files. He too is a member of the Caesar's Legion veteran faction and offers similar dialogue options such as giving the player various items. This version, however, was set to appear in the Fort.
Playstation 3 When updating the game into a newer version, and then creating a new game, Atticus or any other safehouse keepers will no longer appear. Removing and re-installing the patches will fix this. [verified]
