How Rebirth Actually Works in The Sims 4 — And Why It Keeps Breaking
Your Sim dies in Life & Death, a pop-up offers you a glowing "Rebirth" option, and it's tempting to click it the same way you'd click "add a new Sim" — treat it like a reset button and move on. Then you actually try it, and either the requirements don't make sense yet, or worse, the feature straight-up doesn't do what it's supposed to.
Rebirth isn't a reset button, and understanding why takes clearing up two separate things: what the mechanic is actually supposed to do, and the fact that it's been shipping with a real, still-unresolved bug that a lot of players run into before they even get the chance to understand the system properly.
Rebirth Is Gated Behind Progress, Not Just Death
The single biggest misconception is that any Sim can Rebirth once they die. They can't. Rebirth is locked behind the Soul's Journey system, and a Sim has to reach the "Dreams Fulfilled" milestone — the phoenix-icon tier — before the option becomes available at all. Getting there means working through a living Bucket List of larger, story-sized goals, not the small daily wants a Sim generates on their own.
If a Sim dies before hitting that milestone, they don't just miss out permanently — as a Ghost, they can keep progressing through Unfinished Business, the ghost-state version of their Bucket List, and unlock Rebirth eligibility later even after death.
Two Ways In, Same Requirement Either Way
Once a Sim has cleared that bar, there are two separate doors to the same outcome:
Choose Rebirth directly from the prompt that appears right after the Sim dies.
Visit the Baleful Bog in Mourningvale, Ravenwood's neighborhood, as a Ghost — submerging there brings up the Rebirth option with the same phoenix icon.
Either path drops you into a full Create-A-Sim session: pick the household they're reborn into (their old family, a different existing family, or a brand-new one), then customize name, appearance, age, and traits from scratch. You're not restricted to starting over as an infant — a reborn Sim can come back as a teen or adult.
What Survives the Transition and What Doesn't
This is the part that separates Rebirth from just deleting a Sim and making a new one: a reborn Sim can retain fragments of their old life. If they'd gone further and picked up the Burning Soul trait during their ghost progression, they carry access to past traits and memories into the new life, and meeting someone from their previous existence can trigger recovered memories. Every reborn Sim also comes with the Reborn trait by default, marking them as having lived before even without Burning Soul.
What doesn't carry over is everything you'd expect from a genuine fresh start — skills, career progress, and most relationships reset, because mechanically this is a new Sim with an inherited backstory, not the same save file continuing under a new face.
The Bug That's Been Frustrating Players For Months
Here's the part search results and patch notes keep circling back to: Rebirth has a documented, persistent bug where triggering it doesn't generate a new Sim at all — instead, the game redirects Create-A-Sim to the first Sim already in the target household, letting you edit an existing Sim rather than build the intended new arrival. Players have been reporting this since shortly after the pack launched, and as of the most recent community discussion, it's still not resolved, which is why complaints about it keep resurfacing in patch-note comment sections months after release.
If Rebirth seems to "not work" for you, this bug — not a misunderstanding of the Soul's Journey requirement — is the more likely explanation, especially if you've already confirmed your Sim hit Dreams Fulfilled and the option still behaves strangely.
Frequently Asked Questions
What's the minimum requirement for a Sim to Rebirth?
A Sim must reach the "Dreams Fulfilled" tier of their Soul's Journey, achieved by completing enough of their living Bucket List or, if they're a Ghost, their Unfinished Business.
Can a reborn Sim remember their past life?
Only partially, and only under specific conditions — a Sim with the Burning Soul trait can retain past traits and recover memories when reconnecting with people from their previous life, while a standard reborn Sim mostly starts fresh aside from the Reborn trait.
Does Rebirth work the same as just making a new Sim?
No. Rebirth carries the option to inherit specific traits, memories, and the Reborn trait depending on Soul's Journey progress, none of which apply to a Sim created from scratch in Create-A-Sim.
Is the Rebirth bug where it doesn't create a new Sim still happening?
As of the most recent community reports, yes — some players are still seeing Rebirth redirect to editing an existing household member instead of generating a new Sim, and it remains an open issue.
