Nightgypsy I detest Social Bunny so I don't use it unless I'm playing certain teen Sims. It makes no sense at all that they get random insults from good friends. So I avoid. I'm on Xbox Series X so I don't use mods. The empty romance bar really annoys me, it's a reminder of the ick! But I keep a backup save and I've been able to switch to that before after unwanted incidents of inappropriateness.
The Bella Goth incident makes me wonder if it's mod related 🤔. On here the advice is always to test without mods to see if the problem persists. We have excellent mod support here:
