Yes, I did. I've also just read a very interesting article on how to fix this using MCCC. Seems I need to first delete the relationship, then go into CAS to create it anew. Then fix the love/friendship levels after the fact. Wish me luck. Should I end up taking them to the gallery, I might as well go back in time to the save that has them first arriving on Earth. As they will lose all of their relationships with other Sims. They just now have two allies, too. Sob.
ImMendota In the reading I did on UI, seems all you can fix is the levels of romance and friendship. I saw nothing that would make them married again. OOFFDDA, but thank you so much for pointing me in the right direction.
