I'm also having this issue. I'm addressing all of the fears the way that they indicate but the negative moodlets will NOT go away. I have Sims angry, sad, and uncomfortable all of the time. They are picking fights with their family members even when I have autonomy off. This has to be a bug right? I get that the wants and fears are supposed to be temporary but there is nothing that is helping.
Same here, I’ve managed to clear cache and repair the game which has allowed me to turn off wants and fears. But I feel even though they do give temp traits which I was aware of, the constant negative moodlets are far too frequent and makes some aspects unplayable because they are constantly extremely sad/angry/uncomfortable and so on.
