Hi.
If your sim has 9 or 10 moodlets at once; and you then become hilarious you will die.
In my extensive experience testing everything I can in this awful game; I recommend that you live in an inexpensive poorly decorated house with low end furniture; because if you live in luxury your sim will always become hilarious and die.
Even if you try to create an evil sad sim that hates all decor types, music etc. They will still somehow become hilarious and die.
My solution; play as a ghost with the Consumed by the Mother Trait from the Strangerville? dlc
Consumed by the mother trait will disable every need, your needs will never decay and you cant die ever again from being too happy... amazing!
I hope this helps you more than "what platform are you on"
Good Luck and All the best to you.
