I'm going to mark this issue as solved as it's related to MCCC
Please head over to MCCC Discord/Page on updates on what to do. I personally don't use the mod and can't help you with it.
i know the update was fixed and my sims aren’t aging now but i play on long life span and long life span is no longer long! instead of being the normal like 96 days for an adult it’s back the same as the normal life span. i want to play on long life span please!! the right amount of long!
Just noticed I had this problem myself!
Like the commenter above me if you have MC Command Center installed then you will need to manually edit the lifespan via the MC Command Center option on your sim's computer. Then you should click the top button "MCCC Settings" and then "Set Age Span Duration..."
The default days for each life state can be found here: https://sims.fandom.com/wiki/Life_stage#The_Sims_4
bit of a pain editing it but it's better than having toddlers that age up in only six days!
