Hey all,
If you started seeing this behavior only after the October 11th patch, please use this thread instead as we are tracking these as 2 separate issues.
I just took another look at the sims who have been doing these mean interactions with ShowSimInfo and noticed they have character values. They were all created in CAS as YAs so they shouldn't have character values. You're right, the autonomous mean behavior is like they behave when kids grow up with negative emotional control. If it happens again, I'll check if these character values are negative when they start being mean for no reason. In both cases, it was triggered after some kind of argument in the household and there was a grudge/negative sentiment involved but was supposedly gone or resolved. I'm starting to wonder if it does something to character values too. Maybe being an occult factors into it too and maybe there's couple of things causing the bug to happen.
It's not happening with these sims now because one I ended up having to start all over again with a new save and with the other, I recovered the save from before Winterfest before Father Winter caused drama in the household with his flirting. But I just checked their hidden info and they all have character values (Two have Emotional Control scores, 65 and -2, and one has Responsibility +3) .
Ok, I did some testing and here's what I found:
I started a new save with two YAs, neither of them are occults. I had them build up a romance and go steady, then had one cheat on the other. It started a very long running grudge on both sides. They had maxed out negative friendship and romance. Eventually I got them to work it out and the sentiments disappeared from their panel. But I saw that they still had the option in the Mean category to "ask what problem is". After waiting a few days after the negative issues were supposedly resolved, one started being autonomously mean to the other.
I aged them down as teens, nothing was really out of the ordinary, one had all neutral character values, one had slightly negative manners because she's a slob. So I don't know if that is by design or not but they do seem to gain character values as a YA. But that turned out not to be my problem either.
I checked with ShowSimInfo and it showed in their hidden relationships info that they both still had hidden grudges against each other. I found a mod the other day that makes it easy to add and remove base game sentiments, so I figured that was worth a try because nothing else I've tried other that restarting or recovering saves has fixed this for me.
The mod worked and I was able to remove those stuck hidden sentiments from them. Thank goodness!!
So in my case, it is definitely tied to sentiments that are supposed to be worked out but aren't and they are "hidden". These were just two regular YAs I put in a new save together for testing purposes.
The mod can be found over at MTS and it's called Easy Sentiments Cheats. So I'd say if nothing else works, look this mod up and give it a try.
