know of a mod that will let sims sleep in double beds regardless of their friendship rating?

Hi I'm getting back into the game after leaving it for a while (Haven't played it since Pets was freshly new.) and now i'm noticing a little problem:

Sims will not sleep double in a double bed. WHAT IS THE PROBLEM?! It worked in past versions, now whats my sim's beef ?! what now do I have to buy single beds for each one of them, making double beds all but useless??
