PapermcFixes

PapermcFixes is a lightweight, zero-gameplay-change optimization and bug-correction plugin for Paper servers. It focuses on fixing long-standing vanilla quirks, tightening up server logic, and smoothing out performance bottlenecks, without altering the core Minecraft experience. Every fix is modular, toggleable, and designed to be safe for SMPs, technical servers, and large communities.

PapermcFixes is fully drag-and-drop. No setup, no dependencies, no config headaches. Drop it into your plugins folder and it immediately begins running quietly in the background, applying stability fixes and micro-optimizations without requiring any attention from you.
