As of the latest 2024/2025 updates, the save file structure has been largely stabilized, but you must ensure you are using the correct version of an editor. Using an outdated editor will either do nothing or, worse, completely wipe your repentance.save file.

Download the modified file (usually named repentance_edited.save). Rename it to repentance.save (overwrite the old one) and paste it back into the remote folder.
