Wrong Yellow v1.0.0-rc2 — Server Entry Hotfix

Second release candidate for Wrong Yellow.

This build focuses on server compatibility and fixes issues that could prevent the datapack from loading correctly on Paper 1.21.11.

Fixed

  • Fixed invalid backrooms:blink/raycast_remove/... functions rejected by Paper 1.21.11.
  • Replaced invalid conditional setblock ... replace minecraft:light[level=0] syntax with explicit execute if block ... run setblock ... replace checks.
  • Keeps the marker-free minecraft:light[level=0] lamp flicker system.
  • Keeps the irregular defective blink rhythm.

Unchanged

  • Entity behavior was not modified.
  • Fake death behavior was not modified.
  • Portal / transition logic was not modified.
  • Fault generation was not modified.
  • World generation and structure generation were not modified.

Known limitations

  • This is still a release candidate, not a fully tested stable release.
  • World generation can still be heavy on modest machines.
  • Feedback is welcome before the stable v1.0.0 release.
