[RL] Sims changes Dynasties/Constant message after loading

I thought it would be worth explaining the issue I' having. So these are the following dynasty issues I'm having: 

1. I gave Cordelia and Thiago a son (Asa). He should be in the Thebe dynasty, and so should his wife (Thalia Achoa). Thalia was originally part of my own dynasty but has married into the Thebe dynasty. Asa is now (for some reason) part of the Abrantes dynasty, but also somehow heir to the Thebe dynasty. Thalia is back to being in the Achoa dynasty. Thiago is in both the Thebe dynasty and the Abrantes.

2. Sofia Abrantes married a sim from my own dynasty (Achoa), so she then became part of that dynasty. She has also left the Abrantes dynasty irl weeks before they got married. Sofia is now in both the Abrantes dynasty (from the world map) and the Achoa dynasty (from the simology panel). 

3. My sim, Reid Achoa, married Dante Monty and became part of the Monty dynasty. Reid is now part of the Achoa dynasty again. 

Mostly it seems that they revert back to their parents dynasties, like with Reid from point 3. However, Asa is somehow part of both his parent's dynasties, and Sofia has different dynasties depending on if you look at her household from the world map or her simology panel. It's a big mess essentially, but I thought actually laying out the issues I was having might help more. :)
