Not sure what triggered it. Sorry I was unable to take a snapshot of it. When I got close to the White King, Breno and Hirge began attacking me for no damage. I tried everything to make them stop. Nothing. Became really hard to kill my enemies!! Once Hirge died and revived she stopped and was normal. But Breno continued and wouldn't die because enemies stopped attacking him. So I shoved him in the fire. Once he revived he was normal again. Later during fight with red dragons Breno did it again. Never happened before or after those two events.
