      The bug

      You can cause a desync by repeatably picking up liquids.

      How to reproduce:

      1. Fly over an ocean and look down
      2. Hold an empty bucket in your hand
      3. Repeatably right click with ~250ms delay between clicks.
        You will have a desync. You will see and air pocket where it doesn’t look like there is water even though there should be.
