[2.2.13] Part of your Stats for Save Files resets when loading a level that has a intermission cutscene.
Notable level packs that I know of that have cutscenes are...
Equinox: Each level has a cutscene when you begin them.
Tortured Planet: Has a cutscene when you start a zone from Act 1.
If a level is loaded that has a cutscene... your stats such as Lives & Score will reset back to their defaults. Any other level that doesn't have a cutscene will still keep your stats that you originally had upon loading the save.
Emeralds are at least kept though.
