Thanks for all the input. I'm testing (again) in a mod-free, repaired game and will report back. This is very timely because I opened my game today to find out Layne Coffin left Olive Specter and moved in with Judith Ward, they had a baby. Baako Jang left his wife Anaya in San Myshuno, took their daughter Billie and moved in with my Sim (not an NPC) in Willow Creek. Katrina Caliente had a baby with "someone" and moved in with the Partihaus household in Windenburg. After returning everyone to their original households I wasn't about to easily correct relationships because I'd taken MCCC out. (I'll use cheats to fix them later)
