My Townie Teens Don't Age?

@NeptuneinBloom 

I would guess that the teens that aren't aging have been set as immortal and/or aging turned off.  Since you use MCCC, take a look at them to see if aging and death is disabled by checking to see if they have any flags on them.  You can also see this if you have the SimsInfo mod.  If they do have aging off or have been set as immortal via flags, you can clear those flags with MCCC if you want them to age and eventually die.

Hope this helps.

Hey! I have the same problem and it definitely has something to do with high school ep. If I go to the graduation event and see "classmates" there, they become young adults but it seems if they don't go to the graduation they're permanently stuck as teens. I have no solution but at least from what I've noticed the graduation event seems to be what's causing this 😞

Same here.

I also think this has been happening since HSY.

However, I noticed the problem only seems to concern the "homeless" teens, and not the ones who are in households.

It's quite problematic. Maybe Deaderpool should be reported, but I don't know how to contact him.

I noticed this with a teen in my game when my main save was fairly new. It was particularly interesting as she lived on her own in an apartment. She wasn’t one of the pre-made teens, just a randomly generated one. The other, pre-made teens aged as normal, just this one teen who didn’t. I was able to tell as I kept tabs on her age by checking MCCC. She stayed at 0/52 (I play on Long) and the others aged like usual. Eventually I just deleted her.

@Lucy_HenleyStrange, your problem is not the same as mine.
Teens don't stay at "0", but gain days without aging (for example, the last one i saw was at 106/21 when i checked MCCC).

Maybe your sim, for some reason, was immortal ?

I know, for example, that vampires stay at 0/X.

It's definitely high school years that's causing this. I disabled the pack to test on the save and immediately every teen that was stuck aged up. I guess the only solution i can think of at the moment is to just not play with the pack, but that kinda sucks.

I think I figured it out! At least, this seemed to work on my end, I don't know if it will on everyone else's. 

But basically, my computer lagged while I was backing up my game and I lost my saves, mods, and tray. 

I was super distraught, but when I reinstalled everything (mods included), I didn't have a teen, so I ddin't bother placing a custom high school.

I played through my generation, had a child, and when they got to high school I kind of forgot that I never did replace the OG one and I was surprised to find everyone had the right age. 

I did test it with another save, and everyone had the right age then too. 

I don't know if the solution was just deleting every important file or playing with the high school that shipped with the pack, but either way, one of these two options worked 😅
