Unlocks disappearing out of nowhere

[moonsetter]

As the title says, many of my unlocks just disappeared? I had just finished a pretty good run with Judas, closed the game normally, and when I opened it again I found that I was missing a lot of the post-it marks I had already unlocked. I'm not sure but I think it might be everything related to Repentance, including characters... It's a lot and I don't want to have to unlock everything all over again.

I've looked through the discussions here and tried two solutions offered in different threads. One was entering "stats" and then "secrets", which supposedly should make everything sync? The other was overwriting the current save file with the most recent backup save file. It seems that the most recent backup file was made after this weird reset so unfortunately it didn't work for me.

I'm thinking about trying this second method again, only with a previous file, but before I do that I just want to ask in case that someone knows a method I could use without losing what I unlocked today. (It was only one thing so it would be a really small loss in comparison to... everything I've unlocked in Repentance)

My Steam achievements are all still there, I think.

Thank you in advance.

This unlocks Steam achievements based on your in-game unlocked secrets. Nothing else.
Useless here.

That's your best option. At least the cleanest one.

If you got some Steam achievements today and lost the corresponding in-game secrets, you could press alt+F2 in the stats menu. This forces the game to read your Steam achievements and unlock in-game secrets accordingly.
However, expect visual inconsistencies: corresponding completion marks will not appear, and completed challenges will not be crossed out.
It's a bit of a mess, but since secrets are unlocked, stuff can be generated during runs.


Note:
The most common origin of the "can't save data" issue are paranoid antivirus programs. Might want to add Isaac to your antivirus whitelist, so it doesn't interfere anymore, just in case.
"But it never did that before" is irrelevant. Updates happen, they can go crazy at any moment.

Seems like it worked! I lost what I unlocked today but that's fine, I'm just glad everything else is fine. Thank you for the advice! I'll also add it to my antivirus whitelist, better safe than sorry.
