The sims 3: Roads don't let me see anything!

@L3anDr0o  I would think there'd be at least one more update, given the initial interest from people who do work for EA in gathering info.  There may have been an Origin update a few weeks ago, or even a something that looked like a game update, but Sims 3 itself didn't change at all: it wasn't a real patch like we're hoping happens.

The aging manager can be finicky, and once it stops working, it's sometimes difficult or even impossible to fix.  One thing you can try is disabling aging entirely, playing for a sim-day or two, and reenabling it.  Immediately before and after both disabling and reenabling the setting, quit to desktop and delete the five cache files in your Sims 3 user folder in Documents > Electronic Arts.  For reference, these files are:

• CASPartCache.package
• compositorCache.package
• scriptCache.package
• simCompositorCache.package
• socialCache.package

Before starting, use "save as" to rename the save, so you preserve the original version while experimenting on a copy.  That way, if something goes wrong, you can revert back to the original with no harm done.

The only surefire way I know of to fix the problem of sims not aging within a save is to install NRaas StoryProgression, which has its own aging manager.  It's a heavy mod though, with lots of other features that you may want to look into before installing it.

You may find some suggestions somewhere that uninstalling Generations and reinstalling it later helps.  The problem with that approach is that removing an expansion from an ongoing save can corrupt the save or the sims in it, as their data related to the missing pack becomes stranded.  Generations has less of an impact than other packs, but temporarily removing it could still introduce issues that even reinstalling it won't fix.
