Weird thing with Losha Vallas, Calabim heroine: My enemy owned her, with a lot of xp already. I killed her once and she respawned in his capital. Great. Some time later he became my vassal and again later he built Hemah - and in the same turn there was a message "Barbarian has created Losha Vallas" (which shouldn't be possible, as she's the Calabim hero!). Next turn this barbarian heroine attacked a paladin of mine (with quite some promotions already) and killed him. She then was dispatched by a close by ally.
