[RL] Sims changes Dynasties/Constant message after loading

I mean, all they have to do to replicate it is either start a new game and play the Thebe Household (Thiago will be listed as the Thebe Dynasty Heir like intended, but also a member of the Abrantes Dynasty), or take one look at the Save I provided (the current Household will get the popups, and you can look in almost all of the Sparks Family Dynasties and see Sims in multiple).

And honestly, this bug is KIND OF game-breaking, because there's no telling how it will respond once fixed (like, HOW is it gonna know where to put Sims who were accidentally put in multiple Dynasties?) And it feels like the likely cause is the "fix" they did for children of pre-made Sims not being put in their parents' Dynasty. It's applying that fix to ALL Sims now, and overriding the usual limit. Just revert that one fix until it can be made stable, because kids of pre-made townies not being automatically put in their Dynasties is the lesser evil by a FAIR amount.
