About this Mod

PlayerInventorySync 🔄

You know that moment where you place a block, it vanishes,
and you have to walk over to a chest to find where it went? 😤
Or when you scoop a bucket of lava and suddenly… nope, bucket’s empty?

PlayerInventorySync fixes those annoying inventory desyncs by instantly snapping your inventory back in sync when Minecraft gets confused.


🚫 Prevents:

  • Placing blocks that vanish into thin air 🪄✨
  • Buckets scooping from the wrong source (or not at all) 🪣🔥
  • Items teleporting to random slots or containers 📦
  • Having to open a chest just to fix your hotbar 🙄

📦 Installation

  • Works on both servers and singleplayer.
  • Just drop into your mods folder and play.

Clean. Single-purpose. No nonsense.
