Create: Metallurgy Fix

Create: Metallurgy Fix

A standalone compatibility patch that makes Create: Metallurgy 0.0.7-HF work with Create 6.0.5 and above — no modifications to the original mod required.

What does this do?

Create 6.0.5 removed a method that Create: Metallurgy 0.0.7-HF was compiled against — TagGen.tagBlockAndItem(String[]) — causing the game to crash on startup with a NoSuchMethodError before any world even loads.

This mod uses a Forge coremod to silently inject that missing method back into Create’s TagGen class at runtime, the moment it is loaded by the JVM. The injected method reconstructs the original behaviour by delegating to the modern tagBlockAndItem(Map) API that still exists in Create 6.0.5+. Create: Metallurgy then initialises exactly as its author intended.

Neither the Create jar nor the Create: Metallurgy jar is modified in any way.

Installation

1. Keep your existing createmetallurgy-0.0.7-HF-1.20.1.jar in your mods folder — do not remove it.
2. Drop metallurgy-fix-x.x.x.jar into the same mods folder alongside it.
3. Launch. Done.

Requirements

Why does this exist as a separate mod?

The cleanest long-term fix would be a recompile of Create: Metallurgy against the new Create API. Until that happens, this coremod bridges the gap without touching either jar — making it safe to update Create independently and easy to remove once an official fix is released.

Compatibility

• ✅ Works alongside the unmodified Create: Metallurgy 0.0.7-HF jar
• ✅ Compatible with Create 6.0.5 through 6.x
• ✅ No world data is affected — all blocks and items register normally
• ✅ Server and client both supported
