Machinery is an ongoing requirement for industry, not just a construction cost. Keep replacements available and check the actual reward and supply options before opening more factories.
Based on the sources below. Planning suggestions are editorial guidance; this is not a claim of hands-on testing on the latest build.
Inspect maintenance before adding capacity
A factory can have raw materials available and still need Machinery. Open the stalled building's panel and check its status. If maintenance is the problem, doubling the production chain creates more demand for the same missing resource.
Use early supply opportunities deliberately
Before late-game production becomes available, the Claws are an important source of Machinery through supplies and tax rewards. Inspect the current offer rather than assuming the cheapest package always includes it. Reward quantities and availability can differ.
- Read incoming supply contents and charges.
- Check tax reward choices for Machinery.
- Keep a reserve for buildings already operating.
- Review supplies before winter.
Balance expansion against recurring demand
Factories can increase industrial taxes while consuming inputs and maintenance resources. Our suggested expansion test is whether you can support the next building without starving an existing chain of its replacement parts. Build around a demonstrated shortage in useful output, not simply an available blueprint.
Recover from a shortage methodically
Identify the buildings whose operation matters most immediately, then inspect the next realistic source of parts. Review expensive supply commitments alongside the next tax bill. Once the shortage is resolved, watch the reserve across several operating cycles to understand how quickly the current industry uses it.
