Re: Auto-Age Is off but sims are still aging

@kelly2799  I've split your post into its own thread, since the other thread was several years old.

Try enabling aging where you don't want it, then quit the game, reload the save, and disable aging again.  You don't need to play through a whole day to see what happens; just fast forward to find out whether it worked.

If that doesn't help, please delete options.ini from Documents\Electronic Arts\The Sims 4.  You'll need to redo all your settings, but hopefully they'll stick this time.
