[PS5] Missing Save Data

Just loaded up my game and saw that several save files were missing, and my main save file regressed to a previous date. 

I was at level 47 and just finished my second-to-last “Hero of the Veilguard” mission. Now, my latest save file is for level 42 from four days ago and I only have only one “Hero of the Veilguard” complete in that file. That’s two or three story missions and five or so completed character side-arcs that have just vanished into thin air.

Frankly, with the way this stuff works, I have zero hope or expectation of retrieving my  files. I don’t know if I have the energy to push through all that again. It was a lot of progress. I’m seeing posts about similar issues from several months ago. Have there been any updates on this error/bug?
