About

A lightweight Minecraft *.21 Paper/Spigot plugin that fixes the offhand ghost block desync bug. Uses PacketEvents 2.x to intercept USE_ITEM_ON and PLAYER_DIGGING packets — when an offhand interaction is detected, it resyncs the clicked block's real state to the client * tick later, mirroring the server's existing mainhand resync behaviour. Includes multi-block neighbor resyncing for doors, beds, chests, and barrels, plus a per-player 2-tick cooldown to prevent spam.
