RemoveDuplicateMove
by z7087
RemoveDuplicateMove is a Fabric client mod that stops a duplicate movement packet from being sent when a player uses an item in the same tick.
What it does
On Minecraft 1.17 – 1.20.6, the client sends an extra packet carrying the player's position and rotation when a time-based item is used. The packet is removed by this mod, so a bucket placement lines up with the facing the player expects instead of going out of sync with the server.
The mismatch comes from the server not updating the player's yaw until after the tick, so the position sent at the end of the tick arrives too late for the item use. Some anticheat plugins treat the removed packets with suspicion, a problem that also appears with newer clients.
The mod runs on the client only, so servers and other players need nothing installed. It is released under the MIT License, and its source code and issue tracker are public. Latest build is 1.0 for 1.20.6, and the mod is published across the release versions from 1.17 up to 1.20.6.

From version 1.17 to 1.20.6 of Minecraft, the client sends an additional packet containing the player's position and rotation before each time the player attempts to use an item once, designed to fix buckets being placed facing out of sync (the player's position and rotation information is sent at the end of the…
