Something very strange has happened.
My cleric turned into a paladin. Not all the way; she's still a cleric, but she has most of the paladin moves listed alongside her cleric moves.
She's a level 19 cleric, which every skill before the permanent skill selected. She appears to have every cleric move, but only most of the paladin moves; specifically, she has Bless Weapon, Pray, Faith's Blessing, Holy Light, Communal Prayer, and Illuminate.
As paladin moves are better than cleric moves, I'm going to be picking those. (But this is probably a bug.)
