Bug Fixes

Mobs not spawning in BSkyBlock worlds

[PR #541] by @gochi9

The ChunkGenerator was not overriding shouldGenerateMobs(), which defaults to false in the Bukkit API. This silently suppressed vanilla mob spawning in all BSkyBlock-generated worlds. The method now correctly returns true, restoring normal mob spawn behaviour.

Water animals (fish, squid) not spawning naturally

[PR #537] Fixes BentoBox #2593

Fish and squid stopped spawning naturally in BSkyBlock worlds after the 1.21 platform migration. The fix resolves the underlying world generator issue that was preventing water animal spawn conditions from being met.

Other Improvements

  • ⚡ Migrate chunk generator to generateNoise() + BiomeProvider API, replacing the deprecated generateChunkData() + BiomeGrid approach used since older Paper versions [commit 32152b6]
  • 🔺 Update BentoBox API dependency from 2.7.1 to 3.13.0 [commit 407b483]
  • 🔡 Migrate all locale sign text from legacy &c color codes to MiniMessage format across 17 language files
  • Update CI to build on JDK 21 and migrate test stack to JUnit 5 + MockBukkit [PR #549]
