I'm currently playing a household of six sims: 5 YAs and one child.
I disabled Lifestyles awhile but am still struggling with frequent hysteria.
Every single day, at least 2 sims get hysterical and need to stop what they're doing to go calm down in the mirror.
Snowy Escape introduces several new Playful moodlets, and I hate the way the sentiments interact with moodlets to disrupt what the family's trying to do.
I feel like I'm constantly on the verge of losing one of my YA sims to death by hysteria.
In short, I wish we had the option to toggle Sentiments on/off like we do with Lifestyles.
Just because I try to keep my sims happy, they are constantly lapsing into hysteria due to Same Wavelength, Family Fun, and so forth.
Otherwise, I love the Snowy Escape pack: all the Build/Buy items, new CAS stuff, winter sports, and so forth.
