Ideas
I can't stand the Roughhousing Encouraged NAP. It destroys all the relationships I've built up. But even after I get rid of that NAP, damaged relationships will still cause Sims to butt heads.
Because I have Realm Of Magic and Get To Work installed, I created a retail selling potions and the only quick fix to repair relationships is to buy the Forced Friendship potion.
I have mine fighting as well. They're both soulmates, with the companion trait. Been working so hard with them. That's usually the first aspiration I work on when they get together. Well it was all good up until a couple of months ago. Then while they were chatting I noticed a mischief interaction pop up on the side. Then it snowballed from there. The mean interactions started popping up "yell at", "insult" then they got into a knock down drag out. Even after I'm clicking to cancel so much I nearly pounded my mouse through the desk!. One thing I've noticed is their random flirting. But if they're soul mates and companions, married, with kids and hardly argued before or disliked any interaction, why are they randomly flirting with everyone? Once I left my Sims to build up another family. When I left them they had maxed out on friend and love meter. I came back and in that time half the friend meter halfway low and the love meter was maxed red. I have 3 families i work on and over the course of a few months was in chaos, one fam I had were doing great then when I checked back in they were divorced and hated each other. Like what's the deal? Please fix! If anyone has any insight, your help would gladly be appreciated. Thank you.
