@CGrant56 I'm glad that you mentioned other traits. I mentioned veggie because I had just made a veggie sim after a long break from it and was tired of seeing the problems i mentioned. I completely forgot abou major issues I have with the Loner trait, because I haven't played it in so long because, to me, it's completely broken.
My "loner" sim would run out the door when her social bar was full to talk to a stranger. She had no traits like cheerful or friendly or any other traits or LTW that would make her behave like that. It wasn't always like that, "loner" was broken after an update long ago, don't know which one. I haven't used it since. I don't see any other traits as being broken like this, but I don't have all the packs that many simmers have and haven't played all the traits. I'm wondering if content that adds traits compounded this problem.
I also think that automatic charisma learning causes problems in my game. What I mean is, in 4 your sim learns charisma from the beginning by doing certain socials. Repeating certain socials will eventually give you sim a charisma point. In contrast, in TS3, your sim needed to learn charisma from a book or mirror and get a point in before socials will do anything. It seems like after any of my sims get that first charsima point they keep wanting soical and seem bent on upping charisma, and there's no way to stop it, regardless of trait. I should say makes it worse. The loner sim I mentioned had no charisma.
@Psychotps Yeah, the calorie system. it's weird. I have to get a guide on that again, for the sake of my Adult Female sims. The weight issues in my game for Adult Female sims bothers me more than the weird calorie thing. All of my adult female sims have to exercise like crazy to maintain fat and muscle. It doesn't matter whether or not they have Active trait or have the fat burning thing from the bodybuilder LTW it's all the same. She needs to work out twice as long as the Adult Males to be in the same shape.
I also turned off residnetial lot triats a long time ago. Well, I turn them on when needed and off when I don't. I was tired of non-artistic sims autonomously, compulsively painting and having whims to paint when they shared a house with a painter sim. Turned off the lot trait when my artist sim was done painting stopped the issue.
