The Last of Us players have run into a bug which keeps the game from auto-saving. This causes all progress can be lost if it’s not manually saved. Naughty Dog has tweeted that it has addressed the autosave issue, and it was related to servers on its end. “Please quit to XMB and restart the game,” the tweet said. “SP and MP are OK to play!” The issue was not specific to any version of the game, with or with out the day one patch, and further update to the game is needed.
