I have this problem when I use the change traits reward potion. My Sim married an NPC who was a glutton. I had him change his traits with the potion, but he still has the glutton behavior. Had another Sim change his dog lover trait because I was tired of the "giddy" response, he still gets "giddy."
I’m not sure if there is a certain format to use here, but I’d like to add to this frustration.
I do not have CC, never have.
I don’t know how long it’s been happening, because I didn’t realize you could do it for quite a while after I started playing (about a year and a half ago). I’ve had Cats and Dogs, Get to work, and City Living for almost the whole time, so when that’s all that I had for extra content it was already doing it.
Now I’ve added Get together and Strangerville and a few stuff packs
I use CAS to change traits, and it seems to work on some, but not all of them. The ones that stay as moodlets the most often for me are, noncommittal, kleptomaniac, and hot headed.
The weirdest part of it is that if I click on a friend of the person, and see what they know about the problem sim, they will know the new traits that I’ve assigned to them. But if I click on the problem sim’s bio it will still list the old ones that I tried to replace.
CAS has always caused this issue
Here's a workaround that should work: https://answers.ea.com/t5/Bug-Reports/UNSUPPORTED-Changed-Trait-Wrong-Emotion/m-p/4553759#M25810
