I had a sim, Jon Lesson keep on going too. I think he was like 250 days over his day to go. I finally had to age him up and let grimmy come and get him. I do not like doing that, but good grief, when it is time to go, it is time to go.
I did have something else weird happen. My little sim was playing guitar for tips in front of theatre and she stopped because someone was having a baby. It was a friend of hers, so she took her to the hospital, or I should say, walked her to the hospital, anyway, she went in the hospital with her and the friend came out with baby in her arms and the sim that took her got the new baby moodlet. They were not in the same household or anything, but I guess since she took her and witnessed it, it must have given her the moodlet.
