This mod recovers levels and lists lost by BetterSave. It will do this automatically on startup. The recovery will skip duplicate levels and lists, determined by level data, so exact copiables may not be recovered. Note that if you have made tiny changes to a lot of levels, they may not be detected as duplicates, and as such may result in duplicates being added.
For safety, the recovery will not delete the save directory. If you are sure everything has been recovered and want to free up space, you can manually delete the levels
folder from your GD save directory.
