Random Mean Interactions

@wahini2024 , City Living didn't really add an element of fighting , just an element of your neighbors barging into your apartments (like the character Kramer does on the TV show Seinfeld) or being noisy (as anyone who has every lived in an apartment will understand). 😅

The one city that has a larger frequency of fighting is Windenburg, which came with the Get Together EP. 

Also, if you have Seasons, if the minor holiday called Neighborhood Brawl pops up, Sims will be more likely to get into fights.  However, If you notice that holiday on the calendar before it starts, you can delete that holiday if you want! 🙌
There is a lot of taunting and possible fighting if your have Discover University and the other Sims are from the rival school.
Sims will also tend to keep doing activities or interactions that you have them do (I know this is not your case) or that they have done before.  
Also, though I doubt you are doing this, there are certain foods that can make your Sims angry, flirty, energized , etc. (But they can only be made by someone who already has that mood). 

Even though it might not me your CC, I've seen people with outdated CC have weird things happen in their game.  It is best to test to see if your CC is the problem.  
Remove your Mods folder to a safe place like your Desktop
Delete the localthumbcache.package file from your game folder (found in Documents > Electronic Arts >The Sims 4 folder.) This is very important as this localthumbcache.package file can hold bits of corrupted data, even if you get rid of any outdated Mods or CC. 
It can't hurt to repair your game. Fix you game in Origin by logging in and go to Library, then right-click on The Sims 4 and choose the "Repair Game" option from the list.  Wait until Origin finishes repairing all your packs and not just the base game (unless you have a Mac , in which case it will only repair the base game).
Check your game to see if the problem still persists.  If it doesn't then it was the CC/Mod that caused the problem.  You can add your CC/Mods back one at a time and check the game to see which one causes the problem.  If you have a lot of CC you can test in batches (the 50/50 Method). Once you find the outdated CC item, you should delete it and go back to where you got it from to see if they have an updated version and then put that into your game.  😉

Also keep in mind that older save files will start being glitchy.  I don't' know if this file you are playing is an old one or one that is brand new, so it is just something to keep in mind.😊

Please update us on your situation. 😇

@wahini2024  In addition to what @PugLove888 has said.

It really sounds like you have the brawling NAP still active.  So when did you disable the NAPs?  If you did it in game options after you started seeing things, then you were probably too late because NAPs were probably already active.  Using the option has to be done before any NAPs get put into place.

So check on any mailbox to see if any are active.  If they are, they you will need to repeal them.  You can use the instant repeal cheat to do that quickly.  Just turn testing cheats on and right click on the mailbox and select the option.

Another thing that might be happening is the likes/dislikes.  So check a few sims you see doing these actions to see what their likes and dislikes are.  You may have to change some.

Hope this helps.

Thank you! @PugLove888 

I'll for sure do the cache that's one thing I haven't done and likely need to do asap because my sims are self destructive and I'm going through every solution so I can hopefully keep from spending so much time repairing the marriages or friendships or random romance etc.  It's absolute chaos at the moment.  I'll update once I've cleaned up the cache and looked into other suggestions I haven't done 

Thanks! 

@wahini2024 , please also read what @CGrant56 added. 🙂 If deleting the cache doesn't help , then please follow his instructions! 😉

Thank you! @CGrant56  @PugLove888 

This save load didn't start with Naps off. I went through and repealed all of them and then disabled them fully. The Sims I introduced after this are also joining in the random acts of meanness as well. None of them went to university and most have the same likes and there are no dislikes 

I get that they'll be upset with neighbors but I returned in rotation to one Sim who had 3 new romantic interests one of which was despised another hot and cold and one just as an interest... no free love, no brawl, no prank day or brawl day

I'm wondering if the humor and hijinks festival could be doing this? I have 9 families in rotation and they "rank up" certain skills on their own, mischief,  fitness, comedy and charisma. Possibly romance festival? 🤔 they always troll the forums and just literally go from pleasant conversations to your mother is a Llama and I hate your outfit.  It's bizarre 

This load is as old as the day dream decorator was available and was designed to be in the city only for plot reasons.  So it's a newer save 🤷🏼‍♀️

@wahini2024 

Wow.  Since you've done all that, I really don't know what is causing it.  Humor and Hijinxs socials don't usually last beyond the festival so when it ends, those die down to normal.

So, since you didn't say which platform you play on, I'm assuming that you play on a PC or Mac and can use mods.  So one thing I would do is look at the hidden traits on the sims involved to see if they have any residual hidden traits that are NAP related.  You can do that with the SimsInfo mod by Itasan2 at MTS.  The reason I bring this up is that some of the NAP hidden traits used to get stuck on sims and they would keep doing things that the NAP called for like fighting even though the NAP was repealed.  But that got fixed several patches back. But maybe that is happening for you.  Long shot I know but at least worth a try to see if you can identify a cause.

Something that would be good to know if it is happening in just that one zone or world.  So if you travel, does the behavior happen elsewhere or is it just that one zone? Or is it happening in any other world like Willow Creek or Oasis Springs?

Another thing I thought of is you could try is deleting all the NPCs in the Other side of Manage Households.  Not the unplayed premades in houses, but just the Not in World NPCs.  I'd make a copy of the save folder first before trying that though.

Hope this helps.

@CGrant56 

The odd thing is that in my other game loads I don't have this issue.  At all.  Even when Naps were enabled. 

It's only happening in this game load which was created when dream decorate came out.  As for the rest of the world in this load,  I really don't travel to many places out of the city and when I do I'm not playing as someone from... willow creek for example.  I have seen a fight in Windenburg while on a love day date but that's somewhat common even in other loads

Another odd thing...if they vacation in Salvadorea they stop fighting with each other for awhile (pranks don't stop sadly the toilet breaks everywhere) and then it starts back up and sims I'm not playing as will begin to rank up again in mischief, comedy, charisma and fitness. I have one Sim at fitness 7 though I haven't been in rotation with her for her to even reach that level.  However, she is always at the gym when I'm there with another sim as a "townie" 

It's like the vacation breaks the cycle briefly. I still wonder,  only because the skills would match the festivals,  if the festival interactions aren't fading as they should.  

I like your idea. I think I'll create a save and try that to save myself from busted toilets, bacon wrapping fines at work,  random hot cold romance, Llama fines at work and bouts of brawling right after having a nice meal. It would be funny if it wasn't like an infestation and constant.  It does add drama though! I'll also keep this mod link if all else fails.  Even if I could cut the debauchery in half it would be enough 🤪

I'll update after I try it and the cache delete.  Oh, I'm on PC 🙂 

@CGrant56 

Awesome,  thank you.  Between the Nap issues and update and buggy new pack it's been hard to sort out exactly what's gone wrong here

I did dump the cache as @PugLove888 suggested and the game is running better but the interactions, while somewhat less,  are still way overboard.  

I've kicked out of worlds out and I'm about to check the mailbox (none are active right now) and let it run then repeal.  I haven't had kids enter the game because I'm afraid these sims are also terrible parents because they're... well terrible to everyone.  

Here's hoping tonight it gets solved (and 100 times thank you for helping! ) 

Speaking of Naps... would it be common that one area of the city had rough housing while the others didn't? 3 of the areas had the exact same naps and one had totally different Naps... over by the fitness area they had juiced, rough house and I think fun loving but the others had power and water conservation and tech guru. 

Oddly my best behaved and loving sims live in the fitness area next to the Fengs. Strange.  Checking now!
