Sim don’t age/die anymore


My Sim doesn’t age anymore. The age bar is full but the Sim doesn’t age up.


When I try to age him with the birthday cake, I get a message that the Sim is not eligible for aging.


My Sim also doesn’t die. I tried all kinds of methods but he survives everything.


  • Meeting the Nanny makes Sims immortal
  • Sim is pregnant.
  • Sims with the Weirdo-Trait are immortal
  • Sims that repair stuff around San Myshuno are immortal
  • Sims that used to be Detective Career criminal

Immortal Sims usually have a certain hidden trait. This trait can be remove via cheat which in turn lets the Sim age and die again. Don’t try this for pregnant Sims. Wait til the baby is born and the Sim will go back to aging.

Mods that help with the issue

Show/Search Sim Info Mod von Frankk can help you figure out which hidden trait is causing the issue of if there’s a different cause.

Klick on the Sim and choose Show Sim Info – This Sim. You will get an infobox. On the first page you will see if your SIm can age and die.

If it says Disable change to Hidden Traits and check which traits your Sim has. The box should contain info which trait is making your Sim immortal as well as the exact name so you can remove it with the cheat.
