Version 1.2.1+mc1.20.1 – Changelog

Forge Exclusive Version

⚠️ Important Announcement

The expanded world height feature (Y: -128 ~ 1024) is removed in this 1.20.1 Forge update.

• Cause: The function leads to client-server registry desync in multiplayer games, causing biome display anomalies and abnormal disconnections.
• Changes: The mod rolls back to vanilla’s default world height range (Y: -64 ~ 320). It runs stably in single-player and multiplayer, compatible with vanilla servers without this mod.

🧪 How to keep extended world height

The Y=-128 to 1024 world expansion is reserved for the mod’s 1.21.x Forge editions. Full multiplayer support is finished on 1.21.x, requiring the mod installed on both client and server.

If you need tall world on 1.20.1 Forge, keep the old build 1.2.0+mc1.20.1, which is only fit for single-player or experimental tests.

📦 Other Optimizations

• Optimized the auto off-hand totem fill for higher stability.
• Button text refreshes immediately after switching in-game language.
• Item stack limit modifying mixins are moved to server-only to fix registry conflicts.

Thanks for your support. To experience full extended world height, update to the mod’s newest 1.21.x Forge build.
