It is still occurring. I am 3rd generation into a save and all the NPC teenagers at high school are max fat. Even household's I have played before. Obviously I would expect the teenagers to have physiques resembling their parents (give or take). It makes no difference if I take out mods and play vanilla. It makes no difference if my child sim is fit and active, they age up fat. It makes no difference what occult type either. I expect to see an array of different body types. It amazes me that this bug has been around since 2019.

Steps: How can we find the bug ourselves? Play a save through a couple of generations
What happens when the bug occurs? Weight sliders are very high
What do you expect to see? Reasonable weight slider distribution based on parent's genetics.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. Started after 11/7 patch
Since the latest patch (11/7), the weight slider issue has returned. I'm not sure if it's on 100% of sims, but it's more than 50%. Sims are aging up with weight sliders at the 75 or 80% mark. I noticed it when the majority of the high school class in the 3rd generation of the family I'm playing were all pretty chunky. This has been an issue previously, but the old thread was marked as solved for visibility.

Just a quick update. After checking about 50 families, this seems to be close to 100%. Not sure if it's changing on age up, or if they are being created this way. All the toddlers, children, and teens I checked were at 75% or above on the weight slider. Most of them were also very low on the muscle slider (25% ish). Hope that helps.
