Thanks for the information. It looks like I am out of luck with this woman. It's too bad because she was a great Sim -- I made her to look exactly like Ginger Grant. It seems that coming back from the dead not only reduced her to fiance, it made it impossible to ever marry again! After several failed attempts to re-marry her husband, Jorge, I decided to have her cause drama in the house as revenge and to experiment. She cheated on her finance (husband) and seduced his brother, Enrique. Of course she was caught. Anyway, she got her brother-in-law, Enrique, to dump his gay lover, who promptly did (because she was so fabulously charismatic). I tried to get Enrique to marry Ginger, but could get past girlfriend. He got the "go steady", but never got the propose option. They practically woohooed nonstop for days but still no luck getting a proposal. I also changed her name back to Grant (it was Rivera before death). Still no proposal
So I decided to try my luck and see if she could get another sim to marry her. So I thought she should seduce her boss (with the idea that after death, only her career was important to her, to blazes with the family). She invited Yuri Ivanov over. He took to her right way, of course. This time, Enrique caught her with Yuri and slapped her around (no prompting by me). Of course she responded by beating him up in the fight (she is more athletic than he is).
So now I will see if she can get Yuri to marry her. Yuri is currently single.
Meanwhile, the glitch is just with her because her original husband, Jorge, had a second marriage to Ginger's old roommate, Mary Ann, without any problem. It seems that the problem happens when you come back from the dead.
