For some reason, my Sims will be autonomously mean to other members of their family/dynasty for no reason. It is mostly the mother who has the family-oriented and loyal traits and has no negative family dynamics, will start screaming at her husband and children for no reason?? The teens will sometimes start acting mean as well, for no reason at all, but it is not as often as their mother.
One of their dynasty values is to be Diplomatic, but there is nothing in her simology or her rank within the family that contradicts this or would make her act out. She is only mean to people in her family and has no problem with Sims outside the dynasty lmao
