My sim had the gold digger LTW- to see the ghost of his rich spouse. He decided to go after Crumplebottom, I tried fire twice it just didn't work either time, her whole kitchen needed replacing, but she never went up in flames. I had decided to just wait for her to die of old age, until stuff started to break. I had her repair the dishwasher, the trash compactor, and finally a stereo. She repaired the first two items with no problem and little skill, but got shocked by the stereo. It gave her a negative moodlet "singed" IIRC it said it would be a good idea to keep her from repairing things until this went away. I made her try again with the stereo while she still had the moodlet, it shocked her again and she died, the paper reported her death by saying she had been struck by lightning 27 times playing with a lightning rod or something.
Were you able to fulfill the wish? I have not been able to fill this wish even when it seems it should have filled. I have my sims talk to their dead spouses but nothing happens.
One of my sims had this LTW and her husband drowned in the pool. She ran outside when Grimmie came and after seeing him rising as a ghost the LTW filled for her.
