NeoForge 1.21.1 1.1.5-patch5

Official Changelog

For Minecraft 1.21.1 / NeoForge. This remains a Beta build; if you encounter instability that disrupts normal play, return to 1.1.5-patch4.

This republish focuses on survival-balance mining, plugin-state persistence, and RTS camera stutter.

Fixed range and chain mining sometimes becoming completely unresponsive after uninstalling and reinstalling the Remote Control plugin.
- RTS plugin items are no longer mistaken for mining tools.
- Each mining request now owns the correct tool state, so stale tasks cannot leave later mining speed stuck at zero.
Fixed blocks rejected by the harvest-tier check remaining highlighted after mining started.
- The server now reports the exact rejected positions while valid targets continue to preview and execute normally.
Adjusted survival mining plugin tiers.
- Dirt and other blocks without a tool-tier requirement can still be range-mined without a tier plugin.
- The first tier is now explicitly named the Stone Plugin, followed by Iron and Diamond.
- The former Wood Plugin registry ID is intentionally not retained; existing test-world items must be replaced by the new Stone Plugin.
Improved RTS camera input.
- Right-drag now updates the target view directly and stops without release inertia.
- The visual camera advances before each rendered frame, reducing stutter caused by mouse input and the displayed view falling out of sync.
The login notice now identifies the build as 1.1.6-pilot and recommends 1.1.5-patch4 as the rollback version.

Plugin installation, removal, and team migration now persist plugin state and player inventory more promptly, reducing the loss window during a forced server shutdown.
Inventory slots are synchronized immediately after plugin installation or removal.
Local verification passed all 558/558 regular tests and 3/3 performance-debt guards; the related dedicated-server GameTests passed 26/26.
