Hi! Our testing team provided an update and confirmed that the unlimited spell is working as expected.
I wanted to suggest a potential workaround. If the game has a save slot feature, you could try creating a new save game and then attempt to use the trainer to see if it works.
For me, everything works except unlimited spells. The problem might be in calling it āunlimited spellsā, since in my game, only the main character has unlimited spells, not anyone else.
This is confusing since if you turn on unlimited health, that affects everyone in the party.
