Starsand Island 'Unlock the Building Blueprint to Use' Fix

Why does Starsand Island say 'Unlock the building blueprint to use' after you bought a layout or unlocked a plot?

Direct answer

The message 'Unlock the building blueprint to use' usually means the layout and its blueprint state are separate from your plot materials. Community answers point to the carpenter or workshop in town: switch the shop's buy-screen tabs, purchase the layout or blueprint, then select the purchased item from your inventory and place it in build mode. The exact UI wording, Spring Court route, and any missing-registration bug remain Needs verification on the current build.

Evidence: Needs verification

Prerequisites

  • Confirm the exact layout name and the full locked message; Spring Court is one reported example.
  • Record the platform, build, layout price, active quest, and whether the item appears in the inventory or blueprint library.
  • Keep the original save intact while testing shop tabs and placement.

Evidence: Needs verification

Steps and rules

  • Open the carpenter or workshop shop in town and check every buy-screen tab, not only the default materials tab.
  • Purchase the relevant layout or blueprint if it is listed; do not assume that having construction materials unlocks the blueprint.
  • Open the inventory or blueprint library and select the purchased layout, then enter build mode and place it on a valid plot.
  • If the layout still says it is locked, close and reopen the blueprint library and compare the exact message after a restart.
  • For a Spring Court or Moonlit Forest-specific mismatch, record the quest, marker, screen, platform, and build rather than spending materials repeatedly.

Exceptions and branches

  • The carpenter/workshop and shop-tab explanation comes from community answers about a localization or UI mismatch, not a complete official blueprint specification.
  • A layout can require a separate blueprint even when its plot is unlocked and the construction materials are ready.
  • A layout that was bought but cannot be placed may be an inventory-selection, plot, road, or current-build issue; do not merge these into one guaranteed fix.
  • Spring Court and Moonlit Forest marker routes are useful search intents but remain version-sensitive.

Troubleshooting

  • If no blueprint is visible, switch through the carpenter shop's tabs and check the workshop near the general store.
  • If the layout was purchased but remains greyed out, select the item from the inventory or blueprint library before entering placement mode.
  • If placement is blocked, step away from roads or invalid plot edges and test a clear placement area.
  • If a blueprint was found but did not register, reopen the library, restart once, and capture the exact screen, quest, platform, and build.
  • Do not delete a long save or claim a fixed Spring Court location without a current reproducible source.

The error-intent answer

The useful distinction is plot unlocked versus blueprint unlocked versus layout placed. Community reports say the 'unlock the building blueprint to use' wording can persist when the player has materials but has not bought the layout from the correct shop tab or selected it from the inventory. Treat the exact UI behavior as Needs verification until reproduced on the current build.

Evidence: Needs verification

Spring Court search intent

Spring Court is a specific version of this problem: players report that a plot and materials can be ready while the blueprint remains locked. Keep the phrase as a secondary keyword under this broader troubleshooting page rather than creating a duplicate blueprint article.
