Bug Description

A connection crash occurs consistently every time I try to join the "Survival" game mode on the Lifeboat Network server (play.lbsg.net).

The crash is caused by an incompatibility during chunk translation between ViaBedrock and the server's PocketMine-MP software.

• Server Brand: Bedrock @POCKETMINE-MP 4.26.1+dev (v1.26.30)
• Failure: RuntimeException: Error handling chunk data caused by IndexOutOfBoundsException: Index (3) is greater than or equal to list size (2)
• Trigger Path: ChunkTracker.sendChunk() -> ChunkTracker.remapChunk() -> BedrockDataPalette.idAt() -> IndexOutOfBoundsException

Steps to Reproduce

Steps to Reproduce:

1. Connect to Lifeboat Network using Bedrock 1.26.30 via ViaFabricPlus.
2. Attempt to enter the "Survival" game mode.
3. The client disconnects with a DecoderException immediately.

Expected Behavior

The game should successfully load the world chunks and allow me to play the Survival game mode without disconnecting.
