Industry missing from your map?

Decide whether it should exist yet

1. Read the current town demand. Select the town and open Supplies, then inspect the commercial or industrial district that needs the product. Use its actual cargo icons; a product available elsewhere is not automatically needed by this town.
2. Check growth before waiting for another cargo type. Complete useful passenger trips and deliveries of the goods already requested. The XP and ratings checklist helps distinguish stalled growth from a missing factory.
3. Look for the new industry notification and map supply. When demand increases or a new product is requested, inspect the cargo layer and the relevant industry list. The current manual confirms dynamic spawning but does not give a fixed delay or a guaranteed location near the town.
4. Check the climate and the actual recipe. For example, Paper Mill and Printing Press are Subarctic-only in the current manual. Canned Food uses Sheet Metal with Fish or Meat; the Dry climate has no Fishing Grounds. Use the complete canned-food chain instead of searching for an excluded fish supplier or substituting Steel for Sheet Metal.
5. Distinguish starting settings from manual placement. For a new world, New Game → Settings → Civilization contains Industry Density; Gameplay Settings → Economy contains Industry Target Density. For deliberate placement, enable Sandbox Mode in Add Mods and use the world-editing mode guide. Changing density is not a command to spawn a named factory immediately.

How to tell the dependency is met

The town displays the new end-product demand and the necessary industry appears on the map. That is the useful checkpoint; a certain number of days passing is not a published trigger. Then build the route that supplies its inputs and delivers its output.

If it still is not there

• No new town demand: keep diagnosing growth. Completed trips and required-goods deliveries earn XP; weak city ratings can reduce its effect.
• The expected raw material is absent: check whether the climate uses another branch, as with meat instead of fish for canned food on arid maps.
• The town demands the product, but no supplier is visible: search the full map and confirm the game version. Check the active economy and mods as well as the climate. No fixed spawn delay or placement is established here; preserve the save and demand state if the required chain never appears.
• The industry exists but makes too little: switch to the production and booster check; that is a different problem.
