How to install, fix and find answers

Confirm that Enable Custom Content and Mods and Script Mods Allowed are both ON in Game Options. Restart the game completely (not just back to main menu). Also check that the .package file is directly in the Mods folder, not inside a subfolder. The game only scans one level deep.

The most common cause is conflict with another map mod. The Sims 4 only allows one map replacement per world at a time. Remove other replacements for the same world and try again. If it still happens, please submit a bug report with a description and your lastException log.

Some browsers flag .package files as unknown because they’re not a standard file type. The file comes directly from Supabase storage with a signed URL, the same file other patrons download. Click Keep or Allow in the browser warning.

Map replacements rarely break with game updates because they don’t touch script logic. If you see a "made for an older version" warning, you can usually ignore it for map mods. If anything looks broken in-game, file a bug report and I’ll check.

When the game hits an error, it drops a lastException.txt file in your Documents/Electronic Arts/The Sims 4/ folder. Attaching it to a bug report helps me pinpoint conflicts much faster than just a description.

No. Most of my map replacements are around 1 MB and reuse the base game’s geometry, so they don’t add load time or affect performance. You can install several without noticing.

No. Map replacements are visual overrides loaded by the game on top of your saves. They don’t modify save files, sims, builds, or progress. You can install, remove and switch between map mods freely.

No. The new map shows up in any save, new or existing. The next time you visit the world, the replacement is applied automatically.

Yes, as long as they’re for different worlds. Two replacements for the same world will conflict and one will simply not load. Always remove the old version before installing a new one for the same world.

That’s the plan. I’m working through them progressively. The order depends on what feels exciting to me at the time and what ideas I have, not necessarily by release date or popularity. You can vote for upcoming worlds on the homepage to help me prioritise.

The pace is irregular. Some weeks I’ll ship something new, others I won’t touch the project. I try not to leave too long between releases, but this is a hobby and life happens. The Patreon and the homepage always reflect the latest state.

Yes, eventually. They’re much more complex than map replacements and need ongoing maintenance, so I’m taking my time to make sure I have something solid before releasing. No date set.

Map replacements are always free for any Patreon login. Future gameplay mods may have paid early access for higher-tier patrons before becoming free, but nothing is locked behind a paywall permanently.

It lets me track downloads honestly (so I know what to make next) and prevents bots from scraping the file links. You don’t need to be a paying member, any Patreon account works.

The download link is tied to your login, so a copied URL won’t work for someone else. They’ll be redirected to login first. If you want to recommend a mod, share the public mod page (e.g. chatelain-sims.cc/maps/sulani) instead.

Please don’t. I keep everything in one place so I can update it, fix bugs, and keep version history honest. Reuploads end up out of date and create confusion. If you want to recommend the work, link to the mod page on the site or the Patreon post.
