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.
