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.
ps3 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]
