DreamDancer82 Do you have Neighborhood Stories on? Specifically, the accidental deaths option on? If you do, then I find my sims will keep getting that 12 hour sad moodlet every time a sim dies. Usually, it's a couple sims that get killed off by accidental deaths. Many times, it's for sims they don't know but are in their relationship panel because every sim in a zone you travel to gets added to the panel even if you never meet them. So, to get that to stop, I had to turn off accidental deaths.
Hope this helps.
