Minecraft's Anvil chunks (
r.#.#.mca) typically have a
block_entities tag which defines all the blocks in the chunk. Parsers like anvil-parser rely on this.
From minecraft.fandom.com :
block_entities: Each TAG_Compound in this list defines a block entity in the chunk. See Block Entity Format below. If this list is empty, it becomes a list of End tags.
I have downloaded the World file from this page which to my surprise, contained some
.mca files with no block_entities tag. It's in 18.2 format.
What does it mean ? Is the chunk really empty ? It does not have any
end tags either.
Here is the content from NBTExplorer of that chunk :
