Problem has been solved, you can play the game without worrying, there's no need for any kind of precaution and there's no need to download a patch. It was a problem with ND's servers that was fixed on their end.

Again: IT'S FIXED.

Don't just save before quitting, if the bug kicks in you wont be able to save anymore, save whenever you get the chance!

Apparently, the game does save even with this bug. I found a site where the people were saying that the time stamps were all screwed up. If you go to "Load Game" instead of "Continue", you'll be able to find and select the correct save point. Click to expand...

UPDATE 2: yup, staying offline fixes the problem. Do this while you wait for ND's patch.UPDATE: apparently playing offline fixes the problem, still not 100% sure. Disable your internet connection and provide feedback please.Several people have complained about this and it just happened to me, just lost 2 hours of progress.Sometimes the autosave stops working. There's a way to tell if it's happening.Press start, you will bring up the menu. If it says "less than X minutes ago" you're fine. If it's stuck on "autosaving, please wait" you're screwed and have to exit the game. It wont let you exit to the menu and if you try to exit with the PS button it will probably turn off your console but it's the only way.SO HIT START REGULARLY and check if the autosave is updating and save manually, create several separate files just to be safe.God I'm so pissed, I feel like breaking something. 2 fucking hours!how to disable autosave when loading a game:Nevermind, doesn't seem to work. Just save manually often and in the process check if autosaving is still working.we've confirmed that the bug is not being caused by the patch that was released today.we've confirmed that it happens both with physical and digital copies.Hanmik found this on Reddit:Waiting for gaffers to confirm if it works.Update: some people recovered some progress with this but it's not a fix. In some cases it didn't help at all.
