A production chain in Beyond These Stars only works when every stage has inputs, an eligible worker, any required power, room for its main output, and room for every by-product. Global stock is not proof of flow. Diagnose the exact building that stopped, then follow the missing condition one link backward or the blocked output one link forward.
Map the chain before placing it
Start with the final resource and list each prerequisite building. Add power generators and Power Lines where required, storage for intermediate goods, and disposal or consumption for by-products. Then count job slots. A chain that needs more workers than nearby homes can supply is incomplete even when every footprint fits.
Keep frequently exchanged stages reasonably close, but do not compress them into an unreadable block. Roads must reach operating buildings, and future Power Lines, storage, forests, or cleanup facilities need space. Place hazardous or polluting work away from homes while preserving a short logistics corridor.
The technology tree unlocks buildings by constructing and successfully using earlier ones. If the next node remains locked, inspect its highlighted prerequisite line and confirm the predecessor has completed the required action—not merely finished construction.
Separate rate, buffer, and route problems
Rate
Upstream production is slower than downstream consumption. Add capacity only after confirming workers and inputs can support it.
Buffer
A store is empty when demand spikes or full when output arrives. Adjust capacity and filters rather than duplicating the whole chain.
Route
Goods exist but spend too long in transit, sit in the wrong store, or cannot reach a building entrance.
State
The building is paused, unpowered, unstaffed, unfinished, or blocked by a full secondary output.
Observe a full work-and-break cycle before changing several stages. Peeps share their shift rhythm, so a temporary empty building during the break is not the same as a persistent bottleneck.
Use storage as a control surface
Storage is not passive capacity. Configure it to hold the exact intermediates needed in that district and leave room for deliveries. A storage building consumes a worker, so scattering many tiny sheds can worsen the labor shortage it was meant to solve. Warehouses give better capacity and variety once unlocked; Space Ports handle interplanetary flows and can temporarily accept unloaded goods.
Avoid filling every store with abundant basics. Reserve capacity for items that must move through the chain and for by-products that would otherwise stop production. During redesign, resource caches can block demolition, landscaping, or new construction; nearby storage helps Peeps clear the work area.
For imported materials, configure the Space Port and confirm the shipment arrives before building the consumer. A planet-side source and a Kewa-side factory are one chain with a travel buffer in the middle.
Protect power and by-product flow
Power moves automatically through touching powered buildings or connected Power Lines. It is not carried by Peeps. A generator can continue consuming inputs even when the grid cannot store more power, and its excess power disappears. Conversely, advanced generators may depend on powered factories for their own inputs, creating a circular startup risk.
Keep a Burner Generator or another open-loop recovery path available when possible. Trace Power Lines along stable road corridors, and remember that buildings and forests can block them. Check the generator’s by-product output: soot, sludge, or another secondary resource can fill its storage and halt the grid.
Plan a destination for every by-product before scaling the primary resource. A By-Product Yard, configured storage, Cleaner demand, compost route, later recipe, trade, or deliberate pause is part of the chain—not housekeeping after it.
A repeatable troubleshooting order
When output stalls:
- Select the final building and read its current task, staffing, power, inputs, and outputs.
- If input is missing, locate the nearest store and upstream producer; verify filters and production state.
- If output is full, create valid capacity or increase real consumption instead of deleting a random store.
- Check every secondary output on that building and its power source.
- Compare active jobs with housed workers inside the 16-tile employment radius.
- Resume for one full shift and confirm the resource moves into the intended consumer.
Change one constraint at a time so the successful fix remains visible. The Resource Index helps classify materials; By-Products covers secondary-output loops in depth.
