Hey Spinners,
Sorry about the save bug, it should be fixed. Thanks to everyone as always for letting us know these issues.
Note this is actually hotfix 8, we pushed a few silent ones out between this and the last Steam event we made

HOTFIX 8
Fixes
- Fixed Editor saving issues. - It will now save immediately and only when save is requested. - It will notify when the save has occurred. - It will visualize if the current file has unsaved changes (* by the Save or red Save disk). - All changes are autosaved into a Customs\Autosave folder. This is a separate file. - When leaving the editor with unsaved changes, those changes are properly discarded.
- Should now be able to select album art of released tracks in the custom editor.
- Potentially fixed a bug where the track would not appear when going to play a song.
- Fixed music not playing on older versions of macOS.
- Fix input selection on new level complete menu.
- Added CTRL+S (CMD + S on macOS) for saving in editor.
- Fixed some music playback issues when using the editor while the game is resuming after being paused.
- Hold Mouse Click To Move is now defaulted to on.
- Note sounds for hold sections should no longer trigger unless it is actually a lift off note.
Happy spinning!
