been generated and is about to be stored in the {{cWorld|world}}. A plugin may provide some
last-minute finishing touches to the generated data. Note that the chunk is not yet stored in the
world, so regular {{cWorld}} block API will not work! Instead, use the {{cChunkDesc}} object
received as the parameter.</p>
