Is there any way to revive my Sim?
Solution 1:
Use the cheat traits.remove_trait Ghost_Frozen.
You can use the cheat traits.remove_trait X, where X is the trait that caused your Sim to die:
you must use the exact type of death cheat to reverse it.
Use the simology panel if you're unsure.
See this page for more types of death and their trait names, and this page for more info on using cheats.
