🐛 Fixed

Networking

• GUI open codec mismatch — use() (right-click in hand) was encoding the ring ItemStack with STREAM_CODEC while the client constructor decoded it with OPTIONAL_STREAM_CODEC. The wire formats differ, causing a deserialization error and a broken GUI whenever a ring was opened from the hotbar or offhand. Encoding now uses OPTIONAL_STREAM_CODEC on both sides.

Curios Integration

• Unequip callbacks never fired on dedicated servers — CuriosIntegration.init() was called inside FMLClientSetupEvent, a client-only lifecycle event. On dedicated servers the method never ran, so onUnequip callbacks (which reset the smelting state when a ring is removed) were silently skipped. Moved to FMLCommonSetupEvent so callbacks register on both client and server.

Smelting Logic

• Ring limit ignored Blast Furnace and Smoker rings — the hotbar 2-ring cap (non-Curios mode) checked instanceof FurnaceRingItem, so Blast Furnace and Smoker rings bypassed the limit entirely. Check updated to instanceof AbstractFurnaceRingItem.
• Fuel value always queried as SMELTING — getBurnTime(RecipeType.SMELTING) was hardcoded in inventoryTick, meaning Blast Furnace and Smoker rings used the wrong recipe type when consuming fuel. Changed to getBurnTime(getRecipeType()) so each subclass uses its own type.
• BlastFurnaceRingMenu used wrong recipe type — the menu was constructed with RecipeType.SMELTING and RecipeBookType.FURNACE. The recipe book showed smelting recipes instead of blasting recipes, and canSmelt() accepted non-blastable items. Corrected to RecipeType.BLASTING / RecipeBookType.BLAST_FURNACE.

🔧 Internal

• Dead ContainerData in use() — a 30-line anonymous ContainerData was created but never passed to getRingMenu(); BaseFurnaceRingMenu builds its own via createData(). Removed along with the now-unused ContainerData import.
• Redundant instanceof in decodeStack — BaseFurnaceRingMenu.decodeStack(RegistryFriendlyByteBuf) checked instanceof RegistryFriendlyByteBuf on its own parameter (always true) with an unreachable fallback. Collapsed to a direct decode call.
• Magic index in wet-sponge handling — items.set(1, ...) replaced with items.set(FUEL_SLOT, ...) for consistency with the rest of the method.
• Invalid mod version string — mod_version in gradle.properties was neoforge-1.21.1-1.1.0; the neoforge- prefix is not a valid Maven version qualifier and caused a Illegal version number crash at mod load. Changed to 1.21.1-1.1.0.
