OpenPAC ComputerCraft United (OPCCU)

Overview

OpenPAC ComputerCraft United (OPCCU) is a server-side NeoForge mod for Minecraft 1.21.1 that expands Open Parties and Claims (OpenPAC) with better automation support, improved claim management, and survival-friendly tools.

Instead, it acts as an extension that improves compatibility with CC:Tweaked and adds quality-of-life features for claim management while remaining lightweight, configurable, and focused on enhancing the existing OpenPAC experience.
