1. A visit needs a route out
Trace arrival → destination → departure. The useful question is whether the complete journey works with the routing options in your current game.
Try: isolate one broken connection. Check: follow a full visit after changing it.
2. Waiting space and through traffic
Mark the paths used by service customers and other vehicles. A shared conflict is a place to investigate, not proof that a particular road design will work.
Try: move one shared conflict with tools available in your build. Check: completed service visits and the exit queue.
Follow the traffic investigation →3. Fuel supply has several hand-offs
The developer-described chain runs from extraction to refinery to gas station. Start at the earliest missing transfer rather than assuming the final station needs duplicating.
Turn a sketch into a useful test
- Note your scenario and game version. Save before rebuilding.
- Capture the full route before and after, including the entrance and exit.
- Change one connection, waiting area or supply stage.
- Compare equal periods of game time and look for a displaced problem.
