It’s reported that The Last of US has a serious problem on auto-save, in which the game doesn’t do so.
Players have reported that the game doesn’t auto-save, and every progress you made will be lost. Also, it doesn’t seem like manual saving works either once the glitch started.
The problem seems to have something to do with the day one patch, and the connection to the PlayStation Network. While everything is still not confirmed yet, people say that staying offline while playing does the trick, others say that staying offline with the patch installed solved the problem, and others stay offline and delete the patch to get auto-save to work.
It’s unsure what exactly caused the problem at this point, but it’s expected that Naughty Dog to fix the problem as soon as possible.
Meanwhile, who got their copy of the game already?
