What is wrong with this household?
For context: In Fall '23, I created a household consisting of two female Sims. They were married from the start, and both have the loyal trait. They are both family-oriented. This was the second household I added to this save, a couple of months before Lovestruck was released.
However, from the very beginning, both had this inclination to flirt with other Sims - which I didn't let them do. One of them accidentally complimented another Sim on their clothes, but that was just the one time, and I have avoided similar actions ever since. Whenever these two interacted, both had the dialogue option "confess betrayal" even though nothing had happened.
I tried to ignore this, though it really started to annoy me after a while. I have autonomy on, and at some point, I disabled neighbourhood stories for all my played households. I can't remember the exact date, though, but it's been a while.
When Lovestruck came out, things got even more annoying with this household because whenever I didn't play with them, they showed up somewhere in the world stargazing with someone else. One of them even took off to stargaze with someone else while I was playing with them. I disabled attraction so they wouldn't be attracted to other Sims but only to each other. Romance bars are full.
I disabled the option to have Sims from my gallery show up on the dating app because at one point, the game duplicated one of them and put her clone on Sulani while the other one showed up on the dating app. Fun fact: the game did this only with these two.
Nothing worked. By now, they are both getting options to hit on their best friends, ask random Sims to enter a woohoo partnership, flirt with pretty much everybody... and just now I found out that one of them got married to an NPC Sim somewhere along the way. I have absolutely no idea when, how or why this happened. I didn't even know it was possible for a Sim to have two spouses, and I have no idea who this NPC Sim even is because I don't pay attention to random townies.
Something about this household is SO broken, and I can't figure out what it is. This is pretty much the only household that's behaving completely illogically, and not just when it comes to romance. Recently, I sent both of them to the Realm of Magic to discard their magical powers; they were not honing and using those anyway, so I figured they no longer need them. However, one of them can still use her broomstick for flying, even though her magical abilities are gone and the broomstick is no longer in her inventory.
At this point, I am so annoyed with this household that I hardly ever play with them at all, yet I don't want to abandon them completely because they are part of the world and the storytelling I created over the past years (the save's turning 3 in a couple of months).
If anybody has any idea where these problems might come from and how to solve them, I'd be really grateful. Especially for a solution to the stupid "oh no, I cheated even though I didn't do anything"-bit. Granted, the one who got married to a second Sim off-screen DID cheat, after all, but like I said, the fretting has been there right from the start for both her and her real wife. Since my save is growing and I keep adding households, these two will very likely end up sharing a Sim week with another household which will minimize the annoyance for me. Still, I'd really like to get to the bottom of this.
Oh, and I don't use any mods or CC. I play plain vanilla, verify the files regularly and clear the EA app's cache.
