I need some help with the parents in my sims house and artist's emotions please

@Anitalifegurl I'm guessing it doesn't matter if you only played it once or for multiple hours over a span of years. As long as you had TS3 listed in your Origin account at the time you bought TS4, when you opened the game for the first time, the lamps would've downloaded into your game, one for each pack available for TS3 that you own.

I don't have and never have had TS3, so I'm not 100% positive that's how it worked. It's just how I surmise they were given by reading threads on this forum. :)
