Sims constantly doing mischief

My Sims who don't have the trait and don't have "likes mischief" selected keep autonomously trolling teh forums and using mischievous socials in the middle of a conversation even when I have a whole bunch of other socials already queued up.  All packs owned, no cc or mods ever. 

In every single conversation my sims are having, and I play rotationally with a lot of sims, they have started adding mischievous behavior and pranks to their repetoar, no matter what the conversation is and what their mood is. 

• A romantic conversation between a couple will suddenly be interrupted when one claims to be a criminal mastermind 
• A conversation at a funeral with one person comforting the other, and suddenly one person takes out a hand buzzer and laughs manically
• A parent is disciplining his child but then the next interaction is to pretend slap them

It started with some kids at college so I didn't react that much at first, it's college after all, but now it is in every single conversation, even when I control the sims they throw in these pranks without me being able to stop them. 

I do use mods so my save is useless for EA, but as others are experiencing the same I figure I might as well add my experience too. 

My Sim often insults or shouts at other Sims for no reason too... It's anoying because she doesn't have any negative traits and it's so random! 

Also having this issue.  No mods/cc. Started after last patch. Constant mischief and deception. Everyone is constantly lying about their career and other deception and if left alone immediately get on the computer to troll. Seems to be every sim regardless of traits and they were never like this before. Having difficulty holding a successful party as most guests get tense or angry due to this constant behaviour.

I came here to rant because this ish is ruining my enjoyment of the game today.  The autonomous mischief interactions are constant, happening in conversations where it makes no sense for them to occur from Sims that have no traits or aspirations that relate to mischief.  In one save I'm playing a teen who's dating Jeb Harris and in the middle of their suggestive conversation Jeb decides to monkey around and shove his girlfriend, an interaction I really hate.  (I blame his goofball mom for giving him the mischief skill.)  In another save my adult spellcaster is listening to her foodie/ambitious/family-oriented husband with zero mischief skill discuss his favorite recipes and then suddenly he's lying about his career.  The worst part is that when a sim has a mischief interaction performed on them, they immediately perform a mischief interaction back - even if they dislike mischief.  It gives them the mischief skill and once they have it they start sliding mischief interactions into every conversation forever.  They'll destroy every relationship they have falling into mischief interaction feedback loops.

The only way to mitigate the issue is to keep them from ever developing the mischief skill.  It's impossible to get rid of once they get it even with cheats or mods - the game continues to behave as if they have mischief skill if it's removed through either of those methods - so the only way to keep them from developing it is to exit the game without saving immediately after any autonomous mischief interaction occurs.  It's gotten to a point that I'm saving all the time (any time a sim levels up a skill, achieves a goal milestone, an important life event happens) so that I can nope out of the game anytime someone decides to try scaring their spouse without losing too much progress.  It's absolutely ridiculous.  It's also ridiculous that this is marked 'needs info'.  It's happening on console, PC, mods, no mods, etc.  Just play for an hour it'll happen for you.  Get this under control, EA.    

I also don't get why it even an option to lie about your career to someone who would logically know what you do for a living (autonomously or not)? A stranger, sure, but your wife/son/best friend/mother-in-law... surely they know what you work with? 

Not sure if it's related but I've noticed since the last update (or the release of Adventure Awaits) that when my Sim attempts to talk to another Sim they don't know well yet, the majority of the initial social commands are negative ones instead of pleasant ones, and if I leave Sims unattended in a social situation, more often than not they start fighting. My teen Sim went on a date and within the first few minutes they were in an autonomous brawl (and it wasn't brawl day). It totally tanked the relationship and now they hate each other. 

It's become a constant battle stop my Sims getting nasty with each other, especially when I want to get some romance going.

(No mods or CC, and I never even noticed the "mean bug" way back when that was an issue that was reported resolved, but now I think I might have it in my game.)  My save file is from the day the Fairy expansion was released. 

Seriously, I think the exact same thing any time someone uses that interaction or claim to be a criminal mastermind on a household or family member.  Girl, your Dad knows you're not a criminal mastermind he watched you light the kitchen on fire trying to make eggs and toast ten minutes ago.

I don't understand why this seems to have been abandoned and not being addressed by EA? There is plenty of info and evidence here for it to be dealt with and I also would like to add that it is ruining the game. It happens every single time I play, relationships have been made awkward because of it and it makes playing stressful as I feel like I have to baby and watch them all the time in case something goes wrong. 

Sims are still performing mischief despite disliking it! They just can't stop lying about their careers, even to their family :o
