If you're on the beta branch and have a save file from before the latest update, your save file may have just broken, or things may fail to load entirely.
It's easy to fix:
- From the Title Screen, Start a new game.
- Toggle an Insight on and off (any Insight).
- Quit the game completely.
- Restart the game and your save should be fixed.
If there are any problems at all with this build, please let me know. As far as I know it's totally bug free.
