WorldFinder 0.2.1-1 - Fabric 1.21.11 End structure hotfix

WorldFinder 0.2.1-1 is a dedicated hotfix for Minecraft 1.21.11 on Fabric. It fixes incomplete End structure searches that could affect End Cities, their ship variants, and End Gateways. The equivalent NeoForge build was not affected.

What happened

On Fabric 1.21.11, WorldFinder's offline vanilla reference engine could retain an intermediate biome registry while preparing the End generator. When the structure scanner later validated an End City or checked the biome of an End Gateway candidate, some End biome references could not be resolved.

WorldFinder correctly kept every marker it had already proved, but the affected scan cell ended as a partial result. Users could therefore see valid End City markers while other expected cities or gateways were missing from the map.

This was a loader-specific initialization issue in WorldFinder. It did not change the seed, the world, or Minecraft's actual structure generation.

What changed

WorldFinder now rebuilds its End biome source from the finalized vanilla biome registry before starting structure searches. End City validation and End Gateway placement checks both use that finalized generator, preventing unresolved End biome references from interrupting the scan.

The partial result warning remains available for genuine failures and for intentional safety limits on exceptionally large searches. This hotfix removes the incorrect Fabric 1.21.11 partial results caused by the End biome registry issue.

Updating

This update is recommended for every WorldFinder user on Minecraft 1.21.11 with Fabric. Replace the previous WorldFinder JAR with worldfinder-fabric-1.21.11-0.2.1-1.jar.

No configuration change, cache cleanup, world recreation, seed change, compatibility addon, or server-side installation is required. NeoForge users and users on other Minecraft versions do not need this loader-specific hotfix.
