NeoForge 1.21.1 1.0.2-beta

Official Changelog

For Minecraft 1.21.1 / NeoForge mainline.

This update focuses on storage-scan performance, inventory-open lag in large modpacks, clearer scan feedback, and smoother ultimine behavior.

Added a manual refresh button: the main RTS storage bar and the compact inventory overlay now include an R button to force a linked-storage rescan.
Reduced inventory/creative-inventory open lag: the overlay no longer triggers a full linked-storage scan every time a container or creative inventory screen opens.
Improved large-modpack item classification performance: creative-tab membership is warmed and cached instead of being rebuilt repeatedly.
Added storage scan feedback: refresh, search, sort, and paging requests now show a lightweight scan indicator while waiting for the server response.
Improved Ultimine pacing: chained blocks are now processed in small batches across server ticks instead of finishing the entire chain, drop absorption, and storage refresh in one tick.
Fixed and expanded overlay localization: English, Simplified Chinese, Traditional Chinese Taiwan, and Traditional Chinese Hong Kong resources now cover return/import labels, help text, and scan status.
Manual actions still request fresh data: search, sort, paging, and the new refresh button continue to update linked storage explicitly.
