Inspect the right state
Record the build, city, item, stock and transaction direction. Open the 0.4.5 breakdown so the base amount and displayed modifiers are visible. Keep historical range figures out of the current-price field.
Make the decision
Repeat the comparison under the same conditions if possible, changing only the suspected factor. Note whether the offer came from a storefront or the marketplace. Include any observed difference without inventing a formula to explain a modifier the interface has not exposed.
Verify the result
Attach a reproducible save or sequence through the official reporting channel. The archive’s worksheet can reconcile entered revenue and costs, but a correct arithmetic result does not prove the game used the same inputs.
