Last reviewedTrace one good end to end
- Select the final building and identify its required input.
- Locate the input producer and confirm that it has workers and raw material.
- Follow the road, harbor, or storage route between both buildings.
- Check whether storage or the destination is full.
- Change one bottleneck and observe a complete production cycle.
Separate shortage types
- Production shortage: the input is not created quickly enough.
- Labor shortage: buildings exist but cannot remain staffed.
- Logistics shortage: goods exist but do not reach the destination.
- Demand shortage: finished output has nowhere useful to go.
Avoid permanent-number claims
Building costs, timings, output, and balance can change after patches. This guide teaches the diagnostic order and links the official wiki instead of freezing an undated spreadsheet into search results.
Verification boundary
What still needs live verification
This is a dated independent guide answer. Update-sensitive mechanics, values, availability, and interface paths can change; the current live game and official announcements remain final.
Official descriptions establish stable scope. Interface paths, balance, values, rewards, schedules, and version-specific behavior must still be checked in the current game build.
