[RL] Sims changes Dynasties/Constant message after loading

I have the same problem. I have a non-player vampire family. I previously created a dynasty for the father and his three vampire children. The father also had normal children (not occult ones), who are now dead, and their children and grandchildren live in the world. I didn't add them to the dynasty, but today I launched the game and discovered that about 20 new members had joined the dynasty from family members I didn't add, including some of the father's dead children. I kicked them out, sacrificing my relationship with them and reputation, but after loading another family, they were added back to the dynasty!
