I noticed this too, and I made a thread a few days ago both here and the bug forum. It REALLY needs to be fixed ASAP.
And this isnt what EA intended at all. Below, you can see how my Sim aged before the patch. Not only that, I took an adult Sim in CAS and aged him down to teen and adult, and he looked NOTHING like he was supposed to. The game literally overwrites the Sim's appearance with this bug. This can affect genetics.
How the last Sim aged *BEFORE* the patch:
Ok, from what I can tell in CAS at looks like ALL male ages have this issue. I tried a couple tests, aging a child to a teenager, seeing the eye and jaw glitch, correcting it manually, aging them again, and the jaws protrude out and the eyes shrink over and over and over. No matter how many times I corrected it, or at what age, it would all change on the next age up.
Here are some of the pics below...
This child was born to my main sim family so I brought him into full edit CAS:
I aged him to a teenager and his features are too blocky and nothing like his parents or brothers before the patch:
I then altered his appearance with more of what his parents and siblings have looked like:
Then I returned him to the child state and jumped back to teenager and these facial features stayed. So then I jumped the above teenager image to YA and his features, lips too I have noticed, all changed again. It seems like all their lips thin out also:
Then I altered the face AGAIN (setting him back as close as I could to the teenager look), at this adult stage before making him an older adult, this is how he looked right before aging him again:
And this is what he looked like after:
So it seems most of his genetics are thrown out the window with every age change, and he gets smaller eyes, broader jaw, and thin lips. It's annoying the PLUM out of me!
I imagine it would eventually transfer into the female population too, if the small eyes are part of the fathers' genetics. Eventually everyone in town would have small eyes.
That's exactly what's happened to my female child Sim. Her father was affected with boulder-jaw and squinty-eye syndrome. Unfortunately for her, she took after her father's genes and ended up looking like this.
Yeesh if the eyes are supposed to get smaller as she ages, I'm scared to see her as a teenager. Will she even have eyes?!
Thanks for bringing this issue up. I had no idea this happened. My sims are so close to aging up, so I'm glad I found out about this! Here's my picture contribution.
Ugh my poor sim!
Not sure if it's too late to contribute here but I noticed this with my Don Lothario Sim! I aged him down (and the Calientes) to teens so they could be contemporary with Cassandra Goth. Don later aged up naturally (with a birthday cake). Here he is as a teen and as a young adult.
