Protect chain ingredients
Dairy, sugar and feed products support many recipes, so a modest reserve prevents several machines from stopping at once. The exact target should reflect your level and queue habits.
Question speculative stock
Items saved for an order you have not seen recently may be occupying valuable space. Keep goods tied to a near-term plan and sell quantities that exceed it.
Balance upgrade materials
One type of plank, bolt or tape can accumulate far beyond the others. Retain a realistic set for the next upgrade instead of storing an unlimited imbalance.
Make space before collecting
Clear a few slots before harvesting animals, opening rewards or collecting machine output. Preventing the blockage is faster than making rushed sale decisions afterward.
Keep items with a named job; challenge items stored only because they might become useful someday.
