Autosave problems became apparent today following the game's release. Issues were solved earlier today without the need of a patch; instead, players only need to restart the game and continue the campaign. According to the studio, it was a server-side issue.
"We've addressed the autosave issue, it was related to servers on our end," wrote a representative from the studio. "Please quit to XMB and restart the game. SP and MP are OK to play!"
The Last of Us is out today for PlayStation 3.
