[RL] Sims changes Dynasties/Constant message after loading

Since today's update, any time I switch households and switch back or change lots, I get the "SIM NAME has joined XX Dynasty" pop up for all sims in the dynasty every single time. Super annoying.

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
  •   localthumbcache
  •   Any lastException Files
  •   Any LastCrash files.
• Test your save (you will loose all cc on the save but since you created a backup you can go back to that afterwards) and see if the same error occurs, then report back.

I've followed your instruction and the same thing also happened on vanilla game. 

Good evening, I'm a PC player using only MCCC. Since applying the May 12th patch to The Sims 4, I've been experiencing a very troublesome issue. It's happening even with MCCC removed, so I wanted to report it.

It seems a feature has been added that automatically adds blood relatives to a dynasty, but its effect is far too strong. Every time I load a household or enter and exit CAS, it seems a dynasty joining check for Sims is performed. And all blood relative Sims are automatically added to the dynasty based on the check result. Even Sims who are already the head of another dynasty were no exception. He was added to his father's dynasty, a dynasty he had never belonged to before. And because of this, he can no longer open the control panel for his own dynasty…! This inoperable dynasty still appears to the other members as if he is the head, just as before. However, even if he left his father's dynasty on his own, or if his father's dynasty leader was expelled, his dynasty's control panel did not reactivate. Furthermore, even after leaving or being expelled from a dynasty, reloading the household would erase those changes. The same thing happened with other dynasties; Sims related to two dynasties were re-evaluated each time the household was loaded, and instead of the dynasty I had set, the system would arbitrarily decide which one they belonged to.

I've found two workarounds so far. One is to ensure both parents belong to the same dynasty. The other is to create a new dynasty immediately after the troubled Sim leaves the dynasty on their own. In fact, I gave up on trying to regain control of the uncontrollable dynasty and instead created a new dynasty with the troubled Sim, recruited the previous members, and moved them to the new dynasty. This prevented him from being returned to his father's dynasty.

In short, Sims with descent from multiple dynasties, even if they leave a dynasty on their own, or are banished by the current dynasty's leader, are forcibly returned to the dynasty the system arbitrarily decided upon simply by loading a lot.

It seems the only way to break this loop is for those Sims to create a new dynasty themselves.The power of the patch that automatically joins dynasties is truly too strong.

I also have this issue. I've tried removing the Sims from the dynasties, but as soon as I travel etc when the game loads up again, I get a message about so and so having joined the dynasty. It's incredibly annoying. I've tested it with and without mods plus on a fresh save (no mods) and the issue persists.

I have the same issue, it is a pain in the **bleep**. Has anyone found any proper workarounds? The two dynasties in question for me, both have maximum prestige, so I would rather not have to make a new Dynasty

Look, I used to be a programmer, so I understand that sometimes bug just happen, but a bug like this is ridiculous and how long is it going to be before it's fixed? A week? Yeah right, and monkeys might fly out of my ears.  A month? Unlikely.  Probably six months or more.  

Prove me wrong, EA. 

I have this same issue. I have a household where Cordelia V Thebe and Thiago Abrantes had a child, and then later divorced. Their child was supposed to be a member of the Thebe Dynasty like Cordelia, while Thiago left the Thebe dynasty and became a member of his mother's dynasty, Abrantes.

But ever since the May 12 patch, on every single game load, Cordelia's daughter (Cordelia VI) forcibly joins the Abrantes dynasty. Even if I remove her manually. And even though she appears to somehow be part of both the Thebe and Abrantes dynasties when I look at the Thebe dynasty, in the child's own dynasty menu she shows as just a member of the Abrantes dynasty.

Please revert this patch change that forcibly adds sims into dynasties on every game load. It completely breaks the feature of dynasty heads being able to control who is in their dynasty, 

And yes, this issue occurs with absolutely zero mods or CC.

The same thing is happening for me since the update too, also with no mods :(
