Major Fixes

WorldWeaver Chunk Palette Resize Guard

• Added a defensive guard for Minecraft chunk palette resize requests that do not advance to a larger palette configuration.
• This prevents End feature generation and heavy pregeneration workloads from getting stuck in a recursive PalettedContainer.onResize loop.
• Fixes StackOverflowError crashes while End chunks are upgraded to the minecraft:features stage, especially during Chunky/C2ME pregeneration.
• Moved the palette resize mixin out of the net.minecraft.world.level.chunk package and into the WorldWeaver mixin namespace.
• Fixes client bootstrap crashes caused by Mixin treating Minecraft's chunk package as a mixin-owned package and rejecting direct loads of ChunkGenerators.

BetterEnd End Stone Smelter Reliability

• Fixed End Stone Smelter output checks so item components must match before stacks are merged.
• Fixed output capacity checks to respect both container and item max stack sizes.
• Added a guard that restores missing smelt time totals before active smelting progresses.
• Fixed custom Fabric fuels with exactly 2000 burn ticks so they are accepted consistently.

BetterNether Resource and EMI Fixes

• Fixed BetterNether Japanese and Polish language files that contained invalid JSON syntax.
• Fixed the BetterNether Forge EMI progress arrow so it reflects the forge speedup instead of vanilla furnace timing.
• Hardened BetterNether Forge EMI recipe display against empty ingredient lists and missing client level state.

Audit Hardening Pass

• Removed duplicate BetterEnd colored-lights entries so JSON parsing is deterministic.
• Removed unsafe parallel world access from BetterEnd cave feature generation.
• Replaced BetterEnd constructor wildcard mixin selectors with exact constructor descriptors.
• Replaced BetterNether constructor wildcard mixin selectors with exact constructor descriptors and registered the missing Minecraft client mixin.
• Added bounded NBT readers for structure, world config, and data-fixer loading paths.
• Added bounded BetterNether city-piece enum deserialization for corrupted or unexpected structure NBT.
• Hardened BCLib data-exchange payload dispatch with descriptor checks before casting.
• Hardened BetterNether config and debug-shader file handling with scoped resource closure and structured logging.
• Hardened BetterNether Vanilla Hammers and Vanilla Excavators reflection paths with constructor checks, type validation, and logger output.
• Guarded BetterNether complex model generation against missing model sources or textures.
• Improved BetterNether portal shape scanning by using set-backed portal block tracking.
• Clarified BetterNether anchor-tree line loop bounds to avoid fragile size() - 1 loop conditions.
• Replaced BetterNether registry debug matching based on toString() with direct registry key comparison.
• Added fallback handling for malformed BetterEnd ritual axis data.
• Added defensive publication guards for BetterEnd cave biome cache state.
• Hardened config/world-config path construction against unsafe path segments.
• Added the missing BetterNether asset-license note to the main license file.

Update Recommendation

• Keep all four Remastered mods on 30.3.4 together.
• Replace the previous exported jars with refreshed 30.3.4 jars after rebuilding.
