What if the error message includes 'java.lang.NoClassDefFoundError' instead of 'ClassNotFoundException'? What's the difference?

While similar, 'NoClassDefFoundError' means the class *was* found during compilation but couldn't be loaded at runtime. This often indicates a dependency issue – a mod requires another mod that isn't installed or is an incompatible version. Ensure all required dependencies for your mods are present.
