Ally glitch?

Every time I talk to my king, I get a message that says "X has joined the fight on the enemy side." With x being literally my own faction. I also had a problem where the king was being chased by the Poles, a group of friendlies showed up so I engaged the Poles along with the king and it counted them as the enemy for the numbers. My own faction turned on me and the king in other words...

Yep, that happens, it usually helps to restart the game and reload.
