PlayStation divers, thank you for your patience and assistance while we worked on identifying the cause of the recent save game bug. As we were working with the save game structure, we wanted to ensure that any potential fix would not cause further complications, so your patience with us was greatly appreciated. We’d also like to give special thanks to those in the Subnautica Discord community experiencing the bug who provided save games to help us reproduce the error and ultimately resolve the issue. This fix is now live for Subnautica on PS4. It may take some time to show up in different regions around the world. If you experienced the save game bug and had an error message during the save process, you should now be able to return to those previously “unsavable” files and continue playing without losing any further progress or data.  If you have any feedback or encounter an issue with this update, you can let us know through our in-game feedback, on our Discord, or on our forums.  You can also follow @SubnauticaPS on Twitter, Subnautica PlayStation on Facebook, and sign up for the PlayStation development newsletter for future updates! We'll let you know as soon as the next Subnautica update is released on PlayStation. - Unknown Worlds
