I didn't noticed when this bug started but not since the beginning I guess. In version 1.6.2 beta I never recruited tier 5 regular prisoners or tier 6 noble prisoners even after keeping them monthes in the party. Their "conformity" gauge never fills up.
My guess is that maybe this conformity recruitment system works like passive daily xp and it would explain why only top tier soldiers are involved in this bug because they can't earn more xp.
