The 1.6 update includes a few additions to the Fallout 4 experience. Among these is the new ExitSave feature for PC players. Exiting to the Main Menu or Desktop will result in the creation of an ExitSave, which is loaded and then deleted the next time the game is started. This feature is available on all difficulties. In addition, the update adds 300 names to Codsworth’s vocabulary, and “Add On specific icons” in the Workshop mode.
As for fixes, the 1.6 update fixes an issue where companions could become stuck while walking, making them unable to run. The “Mankind Redefined” and “Boston After Dark” quests have also received fixes. In addition, deleting saved games should no longer result in other saves being deleted at the same time.
