Like I said, try with a completely new folder with nothing in it.First back up the the sims 3 folder and paste it somewhere safe.
Then launch the game to generate a new folder.You won't lose anything because you're backing up the folder.This is the first step everyone had me do when I have/had issues with my game.It helps to narrow down what the issue might be.
Afterwards exit out.Copy your saves folder into your new folder and launch the save.Play for a little while and see if you have the issue if you don't, exit the game.And now move your mods folder back in.And launch again, play again for a bit.If the issue comes back, there's something in your mods folder.At that point remove the mods one by one and go back in and test until you find the culprit.If NRAAS mods are the only mods you have I don't see that being the issue, but it could be custom content.
Have you tried reinstalling the world?
Try clearing out your game cache: http://simswiki.info/wiki.php%3Ftitle%3DGame_Help:Sims_3_Delete_Cache_Files
Have you cleared out the featured items folder? If not, go in and clear that out.And then make the folder readable only.
