What's new

LC²H V4.2.5-LTS

More planner optimizations + worldgen fixes :]

  • Added Lost Cities 7.5.6 / 8.4.5 support + newer DH compatibility
  • Fixed the blender targeting the wrong chunk
  • Reduced repeated city/highway checks, height sampling and async prep
  • Fixed '/forceload add' blocking the server thread.
  • Improved cache/planner handling and stall diagnostics
  • Fixed more chunk-loading (PLEASE SPARE ME FOR THE LOVE OF GOD) + distant terrain issues from #26 :]

Measured improvements [Numbers are different on different setups!]

  • Height reuse: 2.53-3.01× faster, ~94% fewer samples
  • City-potential queries: 1.67-5.56× faster
  • Route lookup: 5.51× faster
  • City-edge distance: 1.69-110.73× faster (Not joking xdd)
