`play` · `0x0D` · **clientbound** (server → client)

Sends updated biome data for one or more chunks. The server sends it when biomes change without a chunk reload, for example after the /fillbiome command. The client replaces the biome data of the listed chunks.

Sent by the server, read by the client. Listen for it with `client.on("ChunksBiomes", (data) => …)` on the receiving side.
