Install in the game only; not needed on the server
GalacticraftCompatibility (GCC) is a Minecraft Forge mod for 1.12.2 that resolves compatibility issues between Galacticraft addons by automatically modifying configuration files.
When you launch the game for the first time with GCC installed, a configuration wizard will guide you through selecting compatible options for your addon setup. Once configured, the settings are saved and applied on the next restart.
