After tonight’s update (12.05.2026) Sims who doesn’t belong to certain dynasties but have some connection to them keep adding even after I try to manually delete them. It goes on and on. Once I leave one family enter another to fix it, it happens again.

Hi! I'm also having this issue. Before the 12th May 2026 update, all of my current sims married into different dynasties. I should have 2 in the Monty dynasty, 2 in my own dynasty, and the other 2 (in a separate household) part of the Thebe dynasty. I loaded the game yesterday morning and noticed they'd all reverted back to their original dynasties (ie. Sofia Abrantes was back in the Abrantes dynasty instead of my own). I re-did all their moves to the correct ones, but when I loaded the game this morning, they're all back in their original places.
It is getting worse every time I leave the gameplay. Right now the only sim who is in right dynasty is my sim who married to Thebe dynasty, her husband and kids who never were in different dynasty also joined Abrantes dynasty. So they are in the right one and in new one but it show just the new one. Please repair it soon, this messes with my game.
Okay I officially tried everything (cleaning, deleting, trying to create dynasties after that) on my own and nothing’s working. At this point I took screenshots of every single dynasty and deleted all of them. Thank you so much EA for ruining my game for me. Yet I’m still here playing it and spend money while you ruin the experience for me and for other players all over and over again. I’m angry, disappointed and at this point I just give up. I hope the hot fix for CAS will include the fix for dynasties as well. I know it’s not the fault of programming team, I hope they try to fix it but things they want to do are probably not acceptable by the company. It’s sad that management is blinded by money and not willing to care just a little bit about players that supported them all over the years. I give up. Fix it.
Hi there karina_anaya97 as you can see by the current status of your bug report it is in the Validating Report stage. This means that Maxis QA are currently doing tests to see if they can replicate the issue on their end.
Ok. Still disappointing, it may take them a lot of time to fix this so it’s valid at this point.
It's exactly the same for me with the Thor Dynasty and the Kappe Dynasty.
It completely ruins the entire EA storyline. And if I try to change it, it keeps happening over and over again, even if I just go into CAS or open a different lot.
It's so annoying!!!😳
If this keeps happening with every major update, I'm done with The Sims 4!
That's exactly right!
I don't get it. More and more expansions have been added to the game over the past 12 years. It just can't work anymore, and the result is that players are getting more and more frustrated.
And I was really looking forward to the expansion pack and the event.
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.

The same can be said for just reverting that one fix though right? They could revert it back and it will still probably cause more issues. As I've said previously the QA team are working on investigating the issue and will have a fix in due time.
I think the reason this is such an upsetting bug is that it kind of makes the Royalty & Legacy pack useless... The only point of the pack is to have legitimate dynasties and lineages (royal or not), otherwise you're it's all your own imagination without any real gameplay (as we all played before the pack). The pack brought a legitimate way to have long-running dynasties and actual gameplay to that aspect of the Sims, but without that function the pack is literally just kind of pretty (re-used) items and crowns that don't fit properly. A £35 expansion pack shouldn't have it's core function break just over a month after it's release, so it's understandable that people are upset by it, regardless of whether it's being looked into or not.
