Partnered Sims turn into siblings

It's good that the posts have been merged, but they've become a "weird" post. Is this merger okay?

I've roughly read through all the posts since your post a year ago,

and I'm wondering if there's a problem with CAS ⇒ Household Management?

Or rather, is there a problem with the program that "recalls" the data?

Or is it a temporary saving issue?

"The Sim is an adult, but has the child attribute of "no romance."

"System Attributes" (system-like Sims)

These are added and overwritten by the system,

and there is nothing the user/player can do about them. "

That's my impression.
