Troubleshooting

The Build Script Cannot Find CS1

Edit the $game path in scripts/build.ps1 so it points to your Cities: Skylines install directory. The script checks for Cities_Data\Managed\ICities.dll before compiling.

The API Does Not Respond

Check these in order:

1. The mod is enabled in the CS1 content manager.
2. A city is loaded.
3. Port 32123 is not already in use.
4. scripts/start-resume.ps1 or scripts/start-new-map.ps1 finished with a /health response.

Roads Look Connected but Traffic Fails

CS1 network crossings are not intersections unless a real node exists. Use:

Invoke-RestMethod "http://127.0.0.1:32123/state/road-anomalies?nearMissDistance=18&shortSegmentLength=32&includeDeadEnds=false"

Then remove the bad segment with /commands/bulldoze and rebuild with endpoints close enough to reuse the intended road nodes.

Service Buildings Intersect Roads

Use:

Invoke-RestMethod http://127.0.0.1:32123/state/building-anomalies?limit=200

Move or replace the building with /commands/move-building or /commands/place-building, then re-check the anomaly endpoint.

Saves Are Not Visible Yet

/commands/save uses CS1's normal save panel path and writes asynchronously. Poll /state/saves after requesting a save, or use:

powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\save-city.ps1 -Name AgentAutoSave-clean
