Selvadorada Vendor

Tends the sales tables and food stall in Selvadorada. May be any local.

⭐Special Case
✅️ Selvadorada resident (even though it's a vacation world).
✅️ Young adult or older (ideally adult)
❌️ Ghost
❌️ In the current household
❌️ Work hours
❌️ Grim Reaper
❌️ Father Winter
❌️ Servo

There's no cheats to use here unfortunately. You cannot have your sim live in Selvadorada too.
However, there is a way to achieve custom sims in this role: merge them into a household "living" in Selvadorada. Simply follow these steps:

1. Travel to Selvadorada to have the game generate Selvadorada households.
2. Take note of sim's names, especially last names. Safe bet is to always look for the vendors in Puerto Llamante Marketplace.
3. Open Manage Households in Manage Worlds and look for households with that last name.
4. Using the Merge Households tool, move in the sims you want to appear as locals in Selvadorada. If you have 8 sims, you may move out that original sim(s) into the household your sim were in.

And that should be enough to have custom local sims appear in Selvadorada.
