Fabric and Forge are different loader families
Minecraft mod loaders provide different APIs and startup systems. A mod packaged for Fabric can declare Fabric-specific entry points and dependencies that a Forge profile does not understand.
The hosted CreativeCore JAR contains Fabric metadata and requires Fabric Loader plus Fabric API, which is a clear sign that it belongs in a Fabric setup.
How to identify the build you have
Check the filename, download page, and the metadata included in the JAR. For this site's file, the filename includes FABRIC and the internal mod metadata lists fabricloader and fabric-api dependencies.
Do not rely only on the CreativeCore version number. The same library version can have loader-specific builds with different packaging.
If your modpack uses Forge
Use a CreativeCore build explicitly released for the Forge version and Minecraft version used by your pack. Also verify the dependent mod expects that same loader family.
Replacing a missing Forge dependency with a Fabric JAR will not solve the requirement and may introduce additional startup errors.
Avoid mixed-loader mod folders
Keep separate launcher instances for Fabric and Forge. Separate folders reduce the chance of accidentally mixing API libraries, loader-specific mods, or configuration files.
Label instances by Minecraft version and loader version so updates are easier to audit later.
Troubleshooting loader mismatch
If the game reports an unrecognized mod, missing Fabric Loader, or incompatible metadata in a Forge profile, remove the Fabric file and install the correct Forge build instead.
If you are unsure which loader a pack uses, check the launcher profile before downloading any library dependency.
