NeoForge 1.21.1 1.1.5-patch2

Official Changelog

For Minecraft 1.21.1 / NeoForge.

This small patch focuses on Sodium rendering recovery, dedicated-server stability, large mining performance, localization, and minor visual polish.

Improved Sodium range-culling compatibility.
- Hidden blocks are now handled more reliably through Sodium’s rendering path.
- Leaving RTS mode rebuilds affected chunk meshes, reducing cases where previously hidden blocks remain invisible.
Improved middle-click block selection.
- Middle-click inventory selection now works more reliably when preparing blocks for RTS placement.
Improved dedicated-server stability.
- RTSBuilding no longer rebuilds creative-tab contents on the server.
- This avoids accidentally triggering client-oriented events and networking behavior from third-party mods during server startup.
Optimized large chain-mining and area-mining jobs.
- Overlapping drop scans are deduplicated.
- Identical drops are grouped into legal stacks before being inserted into linked storage.
- This reduces repeated storage-network operations during large mining jobs.
Completed workflow and GUI-binding localization.
- Workflow types, pause/resume states, missing-material panels, protection messages, and GUI-binding errors now follow the player’s selected language.
- Bound cables and machines now resolve their display names on the client, avoiding Chinese-only names on English clients.
- English, Simplified Chinese, Traditional Chinese (Taiwan), and Traditional Chinese (Hong Kong) are covered.
Refined several plugin and top-bar textures.
Clarified the version information shown in the startup reminder.
