Missing Palette Exception Fix

Have you ever experienced random game crashes without any apparent reason?

Do crash reports often blame mods like "Embeddium", "Rubidium", or other Sodium variants as the cause, even though removing them doesn't actually solve anything?

The error logs might contain messages such as:

• "IllegalStateException: Exception copying block data for section: SectionPos{x=..., y=..., z=...}"
• "Caused by: net.minecraft.world.level.chunk.MissingPaletteEntryException: Missing Palette entry for index ..."

This mod provides a temporary fix for this annoying issue!

What's the core problem?

The exact cause remains unidentified, but the essence is that the server contains blocks that don't exist on the client. When the server sends new chunk data to the client, the client tries to process unknown blocks and suddenly crashes, sometimes even bypassing protective mods like NotEnoughCrashes.

How does the solution work?

Simply add this mod to your mods folder. Instead of crashing the game, all problematic "unknown blocks" will appear as dragon eggs - I chose these specifically because they're impossible to miss. This allows server administrators to use the /setblock command to remove troublesome blocks from the world and restore stability for players who don't have this mod installed.

Admittedly, it's not a perfect solution, but considering the diagnostic complexity (chunk data is stored in binary format, making it difficult to pinpoint the exact position of problematic blocks), this approach helps stabilize the game enough to continue playing.
