I started out with my woman sim, Vivian Winstead. Then an alien appeared and i just had to cheat and add her to my family (I hate to cheat and haven't since). The alien (Sizhut Ewi Bip) married Simis (A human). Then Vivian married some guy who she divorced after getting all his money and his house, but not before she got pregnant with her only son, Devin Winstead. Sizhut and Simis Ewi Bip had their first baby boy (also an alien), Sizauras Ewi Bip. After Sizauras, they got pregnant again. This time with girl twins (both aliens), Sizu-Marie and Siz-Michella. Siz-Michella is dating and soon to be engaged to Devin Winstead since they are only house mates, not related. Both Sizhut and Simis Ewi Bip are elders, and both are long over-do. I want to start a long chain of aliens, but my elder sims just won't die! I don't want to cheat and have them die and I also don't want to move everyone out of the house. I haven't messed with the lifespan's since I began the game. It is set to 91 sim days, and elders are only supposed to live for 2 days. Simis is 97 days old! Sizhut is 93 days old. How do i make them die without starving them or cheating or anything?
