Hmmm.... what an odd new development... I was playing takeda Normal, was doing great, beating the tar out of Imagawa and Hojo. I was laying seige with Shingen when the elder Takeda croaked, and Shingen became Daimyo... well, guess Shingen really hated his pops, cause HE BECAME A RONIN!!! I checked, and rechecked. That's right, he became a ronin daimyo. Belonged to some strange named ronin clan... sigh I wonder if this is a bug or a feature? A heir chooses to become an enemy of the state. Sigh, so I killed him, and the game went on as usual, as Shigen's brother became the next daimyo. DId anyone have similar incident?
