Has anyone noticed townie children not aging up since they installed Late Night?
I have a Sim in my dynasty game and he has been a child for the past three generations. He is not a vampire because he does not have that red glow around him in the relationship panel. I invited him to one party and all the other guests stood and booed at him.
Oh and before you ask he isn't listed as a paper boy or babysitter.

If the Sim should age, there are a few things you might try.
I had this problem with Tay Bayless. Everyone else has aged up properly so far in my game but it is a known problem with LN. I brought this up in the "problems with LN" thread here. (I play the Bayless family as well as the other families with kids or teens. So it's slightly different but I think it's probably the same bug.)
Several people have commented on this problem at the official forum. For some people, only custom Sims don't age up. For others, like me, it seems random. For others, no one will age up.
You can try deleting your cache files (compositorCache.package, scriptCache.package, simcompositorCache.package, and CASPartCache.package). That seems to have helped some people. (I do this fairly often anyway because I get fewer bugs when I do.) Some people also need to delete the DCCache folder. (I'd just rename it instead of deleting it in case you decide to put it back. )
Some people have solved the problem by deleting the above cache files (but not the DCCache for some) and adding the LN exe files to their Data Execution Prevention (DEP) list.
People whose playable Sims don't age can try using "testingcheatsenabled true" and then right clicking on the sim to trigger an age transition or "testingcheatsenabled true" and then typing resetsim [firstname] [lastname] (or resetSim or ResetSim) in the cheat box. Those things have worked for some people (but it seems like not for most people). I'd try that before the other solutions for a playable Sim, though.
All these things helped some people but not others. It seems like there are still a lot of people with the problem even after doing all those things. You may want to look at the official forum because there are threads about this problem there and someone may come up with a solution that will work for you.
