I've got 9 companions of which 8 are Bovo Longriver with the same face and a new guy Tiziano Plaia with a different face.

Is there some difference between these characters? Was there an error or is it intentional to find so many Bovo Longriver clones?

Edit: It's intentional. The characters with different faces have stats bonuses that can be viewed by hovering over the character when you haven't assigned them to a profession yet.

I agree that this needs to be more easily discoverable, added a note for myself. Btw the bonuses are visible also after assigning a profession, however bonuses that are not applicable to the current profession are not shown.
