Storage cap concept
Storage cap is the maximum quantity of a resource your nation can hold at once. Any production or transfers that would push beyond that limit can trigger overflow handling rather than silent accumulation.
Think of cap as a hard container size, not a suggestion. If your economy keeps producing while storage is full, you need either more storage capacity or a planned outflow.
Overflow auto-sell
When overflow auto-sell is enabled by world rules, excess resources above cap are liquidated automatically, usually at market-linked pricing with any applicable handling fees. This is intended to keep state valid and deterministic rather than allowing impossible inventory.
Auto-sell protects consistency but can hurt strategy if it dumps resources you wanted for later use. Check Outcomes and Explain to see which resource overflowed and how much cash resulted.
Prevention
Use a prevention loop before each tick:
- Monitor resources approaching cap, not just currently capped.
- Place planned sell orders before overflow forces timing.
- Shift production focus away from repeatedly capped resources.
- Expand storage-related capacity where available.
- Coordinate build and market actions so output has a destination.
Preventing overflow is usually more profitable than reacting to forced sales. If you repeatedly overflow the same resource, treat that as a planning signal. Your nation is producing faster than your storage and trade cadence can absorb. Either rebalance production or create a standing sell routine so excess has a predictable path out.
During troubleshooting, compare two consecutive ticks where overflow occurred and where it did not. The difference often reveals whether the trigger was production growth, delayed market movement, or a temporary cap bottleneck.
