Switched my wife's class mid game

My wife and I both created characters while the game was downloading, and started playing after it finished the next morning. For some reason, after she had changed her appearance in the mirror, my characters name and voice changed too. Then, after I played and saved my game, her class changed from warrior to mage. She still has warrior abilities equipped, but the mage weapons and skill tree. Loading a previous save didn't help either. Any advice?
