Release 247.2:

• Fix for pre-simulation of liquids removing crop-lights (gleam) during world generation. This was causing the world builder to fail generating some private worlds.
• Fix the presentation of heat in furnaces on survival worlds.
• Fix for the rendering of Atlases of 6km worlds.
• Fix the Creative Bridge distance checking to be consistent between client and server.
• Modifications to the sampling rates of http request to scale better for a larger universe.
• Modifications to the server logging to reduce the volume of verbose logs generated for a larger universe.
• Updated Marble text description to reference the variations.
