Playing with Occult Characters Question

So...try to make this concise and clear: I've played Sims for years now, and I do use mods. However, I almost always eliminate Occult characters from my games 'cause I generally like a more realistic play.

That said, I decided to delve into the occult play with a new game. I started a family, left all the NPC occult toons in place (removed the mods that removed them) and started a game. My family is a split normie/spellcaster family (it's a very Bewitched scenario if you're old enough to get the reference). All is well at the start...

However, I notice that whenever my spellcasters from one side of the family greet non-spellcasters of the other side, they totally plant a romantic kiss on them. The casters don't do that to each other (even if non-family), but for example the spellcaster uncle of my main character greets the normie grandmother of the main character (the uncle and grandmother are from different sides of the family) with a total romantic kiss. Is this an occult feature? Something to do with a mod that I've not found? Anyone else had this experience? Is it by design?

Even with all the mods intact except the occult reduction, this never happens on my normie playthrough unless it's a romantic attempt. It's...a bit creepy. 🙂
