Re: Which mods do you use to keep sims in their homeworlds?

There's a mod that I think will help you! You should check out Zer0. They have a series of mods called "Walkby" mods which prevent, for example, someone from Sulani appearing in Mount Komorebi.

Be sure to read the specifics about the mod and make sure you download the XML injector (linked on the patreon post) if you choose to download it.
