Official Changelog
NeoForge 1.21.1 1.0.3-beta
For Minecraft 1.21.1 / NeoForge.
This beta focuses on multiplayer stability, dedicated server safety, remote GUI cleanup, and several high-priority usability fixes from early player feedback.
- Improved multiplayer RTS camera behavior:
- Reduced idle camera move packets.
- Added a low-frequency idle heartbeat instead of sending no-op movement every tick.
- Throttled local camera restore attempts to reduce camera/POV/audio conflicts with other mods.
- Improved dedicated server / headless server safety:
- Moved client-only GUI, screen, renderer, keybind, and S2C client handler setup behind client-only entry points.
- Common network registration no longer directly loads client screen classes on dedicated servers.
- Fixed remote GUI cleanup for chest-like containers:
- RTS-opened remote menus now track both menu id and source block position.
- Closing the GUI, leaving RTS, or switching screens now forces a server-side close visual update for vanilla/open-count containers.
- This is aimed at fixing chest lids staying open after remote GUI use.
- Fixed Survival Balance disable behavior:
- Turning Survival Balance off now clears cached client progression locks.
- Server sync now sends a disabled/empty lock state instead of preserving stale locked features.
- Refreshing/reopening RTS should no longer keep old locked states after disabling the config.
- Added a configurable maximum RTS action radius:
- New common config:
maxActionRadiusBlocks, default128, range48-512. - When Survival Balance is off, RTS uses this configured max radius.
- When Survival Balance is on, a new max-radius progression node unlocks the configured maximum.
- New common config:
- Improved large-storage count handling:
- Extremely large or effectively infinite storage counts now display as
INF. - Linked storage aggregation uses safer saturated counting to avoid huge number display overflow.
- Extremely large or effectively infinite storage counts now display as
- Added player-inventory fallback when no storage is linked:
- The RTS storage panel now shows backpack items when no chest/AE terminal is bound.
- Placement can use those inventory items, reducing confusion when only the hotbar seemed available.
- Fixed ordinary container overlay count behavior:
- Container overlays no longer mix player backpack counts into linked-storage/container statistics.
- Hover text now distinguishes storage counts from inventory counts.
- Added a client setting to hide the ordinary container/crafting/machine RTS overlay:
- Default is ON.
- Turning it off hides the overlay and stops overlay mouse interception.
- This does not affect the main RTS storage panel.
- Improved collapsed container overlay:
- Collapsed mode now keeps drag, expand, sort, search, refresh, info, and the first linked-storage row.
- It no longer keeps the quick-slot bar.
- Fixed the first linked-storage row drawing outside the collapsed frame.
- Added creative-mode instant remote breaking:
- Creative players now destroy blocks immediately in RTS break mode instead of using survival mining progress.
- Added configurable RTS action keybinds:
- Interact / Place, Break / Mine, Rotate Drag, Pan Drag, Pick Block.
- Added camera up/down controls, default
Space/Left Shift. - Camera vertical movement is synced to the server and works while the RTS screen is open.
- Improved indoor camera control:
- Vertical camera movement allows finer height adjustment.
- Vertical micro-adjustment avoids the old minimum-distance push-away behavior that could shove the camera upward.
- Added the “start RTS camera at player head” client setting.
- Improved settings UI:
- RTS settings controls are now scrollable.
- Title, info, and close buttons remain fixed.
- Mouse wheel over the settings panel no longer zooms the RTS camera.
- Fixed the 1.21.1 config screen blur/layering problem.
- Improved Quick Build / undo discoverability:
- Undo/redo tooltip now shows
Ctrl+Z/Ctrl+Y. - Quick Build tooltips explain that clicking again closes/cancels the preview.
- The
itutorials now mention canceling previews and undoing confirmed batches.
- Undo/redo tooltip now shows
- Added a join reminder for new users:
- Shows the RTS toggle key.
- Points users to the small
itutorial buttons. - Includes Discord / QQ feedback links.
- Can be disabled per world/server.
- Added a warning that 1.0.3-beta is newly released and not widely player-tested yet. If you hit crashes or severe issues, try 1.0.2 and report the bug.
- Updated English, Simplified Chinese, Traditional Chinese Taiwan, and Traditional Chinese Hong Kong language resources.
