Change log:

• Added guardrails around saving and loading data. This should help protect against corrupted save data if something goes wrong, like the save process being interrupted.
  • Backups of the previous save data are also created now, and will be loaded automatically if the original save data fails to load.
• Fixed an issue where spells with a mana cost higher than your current mana couldn’t be discarded even after gaining the “Fate” status.
• Fixed an issue where your supply of spell materials was ignored when duplicating a spell.
