Version 3.0.2

JEI & Recipe Loading Fixes

This version resolves critical issues preventing recipes from appearing in JEI and loading correctly in Minecraft 1.21.

Changes

  • Fixed Recipe Visibility: Resolved an issue where standard Mekanism Elements recipes (like High Performance Adsorbents) were not showing in JEI.
  • Fixed Silent Failures: Corrected the Data Pack folder structure (recipes -> recipe) which caused many files to be silently ignored by the game.
  • Recipe Format Update: Fixed 130+ recipe files that used the legacy "id" key instead of the strict 1.21 "item" key for input ingredients.
  • JEI Crash Fix: Fixed a ClassCastException in the JEI plugin integration.
  • Legacy Key Cleanup: Removed deprecated keys (slurry, gas) from recipe outputs in favor of the standard "id" field.

Technical Notes

  • Implemented custom MSJEIRecipeViewerRecipeType to correctly bridge Mekanism and JEI types.
  • Standardized all recipe JSONs to use strict 1.21 codecs.
