Sims constantly doing mischief | EA Forums - 12578015

Are your sims in a club? If so, what are the club activities?

I have most of them. The ones I don't have are Life & Death, Adventure Awaits, and the Royalty & Legacy. 

So 8 sims, 24 different traits, and they're all doing frequent mischief. What packs do you have, or is it base game only? 

No, I don't have that pack. 

Do you have Royalty and Legacy? Are they all part of a dynasty? If so, what are the dynasty values?

I appreciate the help. It's just weird that its every single sim in my household (I have 8 of them) and they all have different traits/preferences. It wasn't happening before, just in the last few times I have played. 

VeganGoddess963​   You can change doing mischief and other obsessive behaviors a lot by how you assign traits, likes/dislikes and turn ons/offs.  So, take a look at what's assigned to the sims that do something like that.  Another way you can control behaviors like that is to play with autonomy off which will stop active sims but not NPCs.  And a third way to deal with it is mods if you are a mod user.  Each way has its own good and bad points.  So, you'll have to decide what is best for you.

Hope this helps.

What traits does your sim have?
