If you've ever tapped sneak on a laggy server and watched your character crouch twice like it's doing some awkward dance, you already know the pain of Mojang bug MC-159163. No Double Sneak Mod is a simple client-side fix that eliminates the desync between your input and the sneaking animation, so you crouch exactly once — the way it should work. With over 359,000 downloads and active updates through Minecraft 26.1, this lightweight Fabric mod has quietly become a must-have for anyone who plays on busy multiplayer servers.
Key Features
- Eliminates double crouch animation — Fixes the long-standing MC-159163 bug where sneaking desyncs between client and server, causing your player model to crouch twice in quick succession.
- Reliable on high-latency servers — Specifically designed to handle the packet timing issues that occur on laggy or crowded servers, keeping your sneak input clean and responsive.
