[Bug]Members of own party (including player character) are captured

[The Yogi]

After several battles against mountain bandits, my own character (Johan), plus some companions were captured by my own band. Unless set free, these characters will appear as prisoners in the party.

I've had this bug fighting any type of bandit party. It seems to happen after talking or equiping a companion. Next fight, you get this error.

Actually, I've gotten this error without even having a companion, and having companions but not equipping them.
