Continue and Missing Key Pieces

What exactly has been reported?

The player-written guide warns about collected keys resetting after returning through Continue. It is not an official patch note or a verified statement about every kind of save data. Record your installed version and when you resumed if you encounter it. Do not generalize the report into a claim that the entire game never saves.

How do you check the state before restarting?

Separate three questions: which fragments you currently hold, which drawers you opened and which letters you actually read. Those are different milestones. Revisit an accessible drawer and check the letter interaction when possible. A missing achievement can reflect an unread document rather than a missing fragment alone.

What is a sensible plan for another attempt?

Make time for a continuous run and use the stage checklist from the beginning. Pick up fragments when the relevant areas first become available. Avoid replacing or deleting local files based on this guide: no tested save-folder recovery or file-editing method was established in the collected sources.
