Hero's skill was changed

[Lita - Firies]

I recruited a hero from the tavern with the name of Deborah. She was a mage, and had the skill Heart of Darkness when I recruited her.
I paid 800k credits to open up 3 additional rune slots for her, and put her in my formation.
The next day, her skill was changed to Hammer of Darkness. This was a total waste to me, as I already have Catherine with the same skill.
Please change Deborah back to Heart of Darkness. If that can't be done, can my wasted credits be returned to me?

I'm afraid all white mages were patched so they had the Hammer of Darkness skill rather than Heart. The only magi that's supposed to have it is Shayd, a gold hero. You won't get your Mage reverted back to Heart.
