An auto save went wrong and it glitched for a moment before telling me it was out of disk space. There is 400gb free on the disk, so this definitely is not true. I just completed a tough battle and don’t want to redo it but even if I try to save manually it also gives me this error. A black screen that looks like it is part of the PS4 menu comes up with an icon of the game save. Once I dismiss and go back to the game it tells me that there is no disk space left. Is there a way to fix this without quitting the game?
You need to leave the current area you are in. So move to the next area, go to the ark or do something to trigger a load screen. The error will pop up again and when the new area loads, do a manual save. You will notice that the last manual save and auto save are now missing. So save quick before a lot of progress is lost.
