RLTweaker

General Enhancements and Fixes for Minecraft 1.12.2

RLTweaker is a comprehensive toolkit for optimizing Minecraft version 1.12.2 modpacks. The mod's primary focus is on bug elimination, performance improvements, and the addition of useful features for enhanced gameplay experience. While initially developed for RLCraft, the mod is compatible with any other modpack.

Important: The mod operates primarily on the server side! (Some features are available only when installed on the client)

No configuration is required to start - simply add the mod to your pack. All improvements are enabled by default, though it's recommended to run the /rladvisor command after startup for optimal patch configuration recommendations.
