A few minutes into playing after updating, my sim gets a call from her cousin to say that the cousin is now in a relationship with her own brother. I went into the other family to check and sure enough they have a romance bar, and are tagged siblings, sweethearts, and partners. This is NOT okay.

Yeah, I have a young adult/teen relationship that's continued after age up as well as related ones I've seen happen in public spaces with played households too... Autonomous inappropriate romantic interactions. I decided to shut er down and wait for some bug fix updates as with all the other glitches I fear breaking this save.
I have this issue too. The sim I'm playing got a romance bar with his sister and with his father. And when you look at the relationship tree they're gone.
this is still happening for me despite the most reccent patch claiming it has been solved
