My sim has a son who is living with her ex-husband. He grew up from a toddler to a teenager, but it seems like he's been stuck in the teenager phase forever. I breifly screwed around with the aging of my sims, and I was wondering if that somehow messed up the natural aging even when I returned the game to the default settings. Basically, how long is this kid supposed to be a teenager?
As soon as he has an A in school, have him blow out the candles of a birthday cake. That will do it and allow you to choose the trait he develops.. In the first tab, the simology one, it says how close your sim is to aging, but that really only has bearing on young adults, adults, and elders unless you want to keep your sim young for as long as it takes him to age naturally, which would be good if you want him to accumulate lifetime happiness and build skills.
I wish I could have the teen blow out candles and trigger the aging process, but he's not part of the active family. Now it looks like my other sims are having aging issues too. Right before a mother and son were about to age up, their bars were set back to zero for their current stages. Although I don't mind the mother staying younger for a bit, it seems like her kids don't want to grow up...=/
So appearently my sims' age bars reset every time they change their appearence in the mirror, and awesome mod would correct this bug. However, this does not seem to explain why my teen sim from an inactive household is still a teenager, other than the default game setting that keeps him as a teen for a very long time...
