Map Migration
This mod copies the first map from one save into another save and exports the result as a new save file.
What it does
- Opens from RimWorld's Mod Settings menu.
- Lets you choose a source save and a target save from the detected save list.
- Exports the migrated result as a new save name that you enter.
- Saves the exported file into RimWorld's normal Saves folder automatically.
How to use
1. Enable the mod and restart RimWorld if needed.
2. Open Main Menu -> Options -> Mod Settings -> Map Migration.
3. In Detected saves, choose the source save with the Source button.
4. In Detected saves, choose the target save with the Target button.
5. Enter the export save name.
6. Press Start migration.
7. The result will be saved as:
C:\Users\<YourName>\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Saves\<ExportName>.rws
Current behavior
- Copies the source save's meta tag.
- Copies selected game-level tags such as info, rules, scenario, playSettings, storyteller, and others.
- Copies the first your map from the source save into the target save.
- Re-links player faction references for the migrated map.
- Exports to a new .rws save instead of overwriting the selected target save.
Important notes
- Source and target saves must be different.
- Export save name is required.
- The mod is intended for save migration experiments and utility use.
- Complex modded saves may still have edge cases depending on faction refs, pawn refs, or world object structure.
- Keep a separate backup of important saves before using it.
- corpse will be removed
Known limitations
- The mod currently works around one-map migration logic.
- Some heavily modded save structures may require extra compatibility work.
- UI elements such as the colonist bar may still depend on additional save references in specific mod setups.
Recommended usage
- Use on copied saves first, not your only live campaign save.
- Test with the same active mod list on both source and target saves.
If you find a save structure that does not migrate correctly, please share the relevant XML structure or error log.
