Re: Sims won't age since the newest update
Okay, I figured it out! (Wow, that was quick!) And I'm posting the solution here in case someone else runs into this issue after the latest patch update.
If your Sims aren't aging (like, the aging bar is staying gray and they don't have birthdays on the calendar), go under "Game Options" and "Gameplay" and make sure "Auto Age" is turned on on the option you want. It looks like the last patch update they sent out earlier this week turned that option off for some reason.
