Missing dependenciesMissing Forge Multipart (codechicken/multipart/BlockMultipart)
What the log looks like
java\.lang\.NoClassDefFoundError: codechicken/multipart/BlockMultipart
java\.lang\.ClassNotFoundException: codechicken\.multipart\.BlockMultipart
How to fix it
- Download Forge Multipart (ForgeMultipart) for your exact Minecraft version (typically 1.7.10) from a trusted source like CurseForge.
- Place the downloaded ForgeMultipart `.jar` file directly into your instance's `mods` folder (or the `mods/1.7.10` subfolder if using Minecraft 1.7.10).
- Check that CodeChickenCore is also in your `mods` folder—not `coremods`—and matches your Minecraft version, removing any mismatched versions.
- Relaunch Minecraft to confirm the game finishes loading your mods.
