Several new wrinkles and age details can be added to both the upper and lower body for teens and older, which also come in different densities. Stretch marks that were previously introduced in 2023 are now available in lighter and darker tones to match different skin colours. Full-body freckles, previously introduced in The Sims 4: Growing Together, have been expanded and are available to all Base Game players. Rosacea has also been added in a variety of levels of redness.
Ailment Toggle Options
Back in July, The Sims Team released an update that reduced the chance of ailment contagion between Sims. They’ve gone a step further in this update and allowed players to toggle ailments on and off.
The new options can be found in the game setting under ‘Pack Settings’ > ‘Enchanted by Nature’. Here you will see a simple toggle box labelled “Enable Ailment Spread”
If disabled, Ailments will no longer spread contagiously. Once disabled, Sims who already have Ailments will need to wait it out or seek a cure, but no more Sims will contract ailments through spontaneous spread. Being near or interacting with Sims who have an Ailment will no longer have any risk of contagious spread.
Enable Ailment Spread – The Sims 4 Options
Whether or not this is disabled, Fairy Sims in your Household can still give Ailments to other Sims if they have unlocked the Cure or Apply Ailments Fairy Ability. Naturopath Sims who choose to Work From Home will still be able to recieve clients with Ailments who need treatment.
NOTE: Sims who become Very Imbalanced will still contract an Ailement. Uncheck both Enable Balance & Imbalance and Enable Ailment Spread to disable all natural sources of Ailements.
Pack Selector
Players of The Sims 3 will be used to an option similar to this when launching the game. Players of The Sims 4 can now toggle active Expansion, Game, and Stuff Packs, as well as kits, from the main menu if they wish to play without them. Gone are the days of having to use James Turner’s Pack Disabler tool!
To select which packs you wish to enable, head to the menu (…) and choose “Pack Selection”. From this screen (shown below), you can uncheck any of the packs you own that you don’t wish to play with. The game will be required to restart to take effect.
Bug Fixes
Several bug fixes from the laundry list have once again been quashed!
- Fixed Outfit Categories – Recent additions, such as the 25th Anniversary Sneakers and T-shirts, have now been added to more outfit categories.
- Hair Texture Corrections – The curly hair from the 25th Anniversary Update is now correctly labelled as wavy hair type.
- Multiple Students (High School Years) – Players who take four or more teens to an active school day will now all be assigned tasks.
- Fire Tuning (Enchanted by Nature) – Sims with Bad Luck will be less likely to start fires when cooking.

The new update broke my game i cant play any house hold when i try to i press play then it loads then after it loads it kicks me back to the main menu where all the households are
A LOT of people is having this issue, Go to the EA forums and upvote/comment on the threads about it, so they’ll see it. Im having this issue as well.
i found a mod to be the cause of this, once removed im back playing again on all worlds
for me removing these 2 mods (after 11 hours of testing) 🙁 resolved all my issues, hopefully it can help you if you have them:
1) thepancake1-Color-UI-sliders
2) kshuihuh’s RedAppleNet
I did the same thing.. after 2 hours I found out it was: icemunmun_cauldron_herbalism and EvanSki_StopMoldingClay
totally broke my game, i am not even able to play. Anytime you go to enter your household it just sends you back to the choose a world screen and after trying to load into my household for the 3rd time it completely deleted that household. Nice..
i removed some mods and this issue went away, just got to find out which one it is causing havoc, the pancake1-ColorUI-slider was one of them, that got me past the menu, now i can load into worlds again after removing some others, going to be an all day 50/50 challenge again.

It’s the same in germany the update broke my game.
The update broke my game at first. But I tested my Mods and it turned out Twisted Mexi’s mods unfortunately became incompatible after the update. After removing some (but not all) of the TM mods the game loads fine. But the testing I had to do wrecked a lot of my custom builds as it replaced my cc furniture with pale grey EA versions, now I have to rebuild it all!
you wont have to rebuild anything if you dont save, just exit game and nothing else.
I think it’s because I had to remove all the mods and add them back gradually and keep testing to see if the game would load. It defaulted to the generic furniture and didn’t restore the cc furniture even when all my mods were loaded back in. Makes me realise how much better the game is with mods and cc!
haha yeah i feel your pain ive been there before lol, i have posted above in a couple of mods that i managed to track down as issues, with one being the main cause of me not being able to load into worlds, that issue is resolved now, at least for me
I’m having the same problem as many others here, I can’t load into lots. The reddit thread says to remove/turn off script mods but the results seem to be 50/50 on that method.

That worked for me after 2 hours of trying multiple other fixes.
So EA found a good excuse not to fix the packs, deactivate them, EA finally decided to admit that the engine can no longer run so many extensions.
I can’t load any lots now, it goes back to the world selector.
My mods broke for gross wrinkle shit ???
