Ariel Walsh & Xavier Alvaro Disappearing Bug (Isla Paradiso Fix Guide)
Players sometimes find that Ariel Walsh and Xavier Alvaro vanish mid-save in The Sims 3: Island Paradise.
This is caused by routing and population data errors in EA’s original world file.
Here’s what’s happening and how to fix or recover your Sims.
Why It Happens
Isla Paradiso’s world data is corrupted. Broken routing, underwater lots, and stuck houseboats cause Sims to vanish.
NPCs like Ariel Walsh and Xavier Alvaro can be deleted or stuck off-map. Story Progression may remove them entirely.
Mods like NRaas can make the issue appear faster when the world data is already damaged.
Fix & Recovery Options
1. NRaas MasterController – Add Sim
Try to recover them manually:
NRaas > MasterController > Add Sim
Choose Type of Sim: Dead / Service / All
If they appear, re-add them to any household or lot.
Download NRaas MasterController
2. “Total Annihilation” + Restore workaround
If they’re not listed at all:
NRaas > MasterController > Advanced > Total Annihilation
Then manually re-import them from your Library if you have them saved.
3. NRaas Overwatch + ErrorTrap
Install or update both. They automatically fix stuck Sims and clean corrupted data each night.

NRaas ErrorTrap
4. Use NRaas Porter (Move to a New World)
If the world is too broken, move your household to a fixed Isla Paradiso version.
Porter preserves household ties, jobs, and skills.
Download NRaas Porter
5. Download the Fixed Isla Paradiso World
A community creator, Ciane, repaired the world’s routing and population data.

Moving Your Household with NRaas Porter
Step-by-Step
Install NRaas Porter in:
Documents\Electronic Arts\The Sims 3\Mods\Packages
Load your old save.
Select your active Sim > NRaas > Porter > Pack Household / Pack Sims.
Save and quit.
Start a new game in the fixed world.
In Edit Town mode, choose a lot and click:
NRaas > Porter > Unpack File
Pick your packed file and confirm.
Your family and relationships will respawn in the new world.
If you also want their house, save it to your Library before moving.

Tips
Always back up your save before making changes.
Porter only keeps relationships between Sims moved together.
Use Traveler if you want to keep both worlds playable.
After unpacking, let Overwatch and ErrorTrap run a few days to stabilize the new world.
You can check if Ariel and Xavier are restored via:
MasterController > Sim > Basic > Family Tree
A mouthful sorry :)
The only thing is that they don't disappear mid-save. They disappear from the town completely mid-gameplay.
