This exact thing happened to me two days ago. I played some in the morning with multiple quick saves and a manual save, everything seeming normal. Launched the game later that evening and found all of my saves (manual/auto/quick) had reverted to Oct 22, losing 40 hours of gameplay. No apparent issues with my local save file or PlayStation online storage/sync. Cross saves were not turned on at the time, but I turned it on while troubleshooting- appeared to upload the same saves that I could see from Oct. 22. This does NOT appear to be a local save file corruption issue. I submitted a bug ticket but not exactly holding my breath. I was really enjoying this campaign. Now, gutted and disappointed, the prospect of replaying so soon is less than appealing.
Edit: I wanted to also clarify that I attempted all of the known fixes for lost or “unable to load” saves that addressed previous issues reported by others. No luck there.
