Little Logistics 1.21.1.1-beta.2

Pre-release (beta) — first build on Minecraft 1.21.1 / NeoForge. Please test in a non-critical world before relying on it.

This is the first release of Little Logistics for Minecraft 1.21.1 / NeoForge, ported over from the previous 1.20.1 (Forge) build. Alongside the platform update, this release brings a major overhaul of the docking and routing systems, new tutorial content, and a batch of important data-safety fixes. As a beta, please try it in a non-critical world first.

Supersedes 1.21.1.1-beta.1, which failed to publish its Maven artifact due to a dead publish target; no code changes from beta.1 other than that publishing fix.

Minecraft 1.21.1 / NeoForge Update

• Ported the entire mod from Minecraft 1.20.1 (Forge) to Minecraft 1.21.1 (NeoForge).

New Content & Features

• Redesigned docking system: old dock, hopper, and charger variants are unified into a single adaptable multipart dock block plus a matching dock rail. Includes a new in-world configuration GUI (idle-timeout control with presets, selectable redstone modes) and enhanced crane model visuals.
• Routing overhaul: tug and train routing reworked with improved pathfinding, a better UI for selecting destination blocks, and refined route compilation.
• Diagonal tug travel: tugs can now move diagonally, enabling more efficient water routes.
• Route path preview: hold a wrench to visualize the compiled path of a tug or train route item.
• Automatic rail reservations: junction rails now use a reservation system to prevent locomotives from deadlocking and to improve traffic flow.
• Auto-ownership & chunk loading: tugs and locomotives are now automatically owned and chunk-loaded when placed, with new config options for route lookahead and chunk retention.
• Create Ponder tutorials: added Ponder scenes covering tug linking, routing, and docking, and locomotive docking (replacing the old in-game Patchouli guide).
• Dedicated creative tabs: mod items and blocks are now organized into their own creative-mode tabs.
• Added a visual socket detail to the docking-station model, and improved the seater car texture.

Bug Fixes

• Fixed item duplication/loss on chunk unload for the Chest Barge and Chest/Barrel Car — inventory was previously both dropped and kept when the chunk unloaded.
• Fixed fuel/capacitor item duplication on chunk unload for Steam and Energy Locomotives.
• Fixed silent route data loss — waypoints could be dropped when editing tug and locomotive route items.
• Fixed server crash when a locomotive route exceeded the waypoint limit; the route tracker could crash the server tick on very large routes.
• Fixed a client-side native memory leak in route/vehicle rendering that grew every frame while holding a route item or wrench.
• Fixed Chunk Loader Barge data loss — it previously lost its color, spring-link, and entity data on reload; save/load now chains correctly.
• Fixed lost leader spring-link on re-save caused by an NBT key mismatch.
• Fixed locomotive junction deadlocks at rail junctions.
• Fixed route copy recipes and enabled shift-click mass production.
• Fixed custom switch, tee, and junction rails so they properly auto-connect and reshape with vanilla rails.
• Fixed a crash when a solo wagon or barge stalls on its own without a head vehicle.
• Fixed Fluid Tank Car failing to render its fluid contents.
• Fixed synced-data ID collisions on the Fluid Tank Barge and Fluid Tank Car.
• Fixed docking-station crane icon and texture rendering glitches.
• Fixed a tug routing penalty calculation error that affected path selection.
• Fixed dock follower-vehicle binding and settlement accuracy during docking.
• Fixed inconsistent vehicle coupling/linking data.

Balance & Tweaks

• Improved train collision detection and pathfinding accuracy.
• Improved locomotive game-state persistence to prevent desync issues.
• Improved docking physics and tug behavior when approaching docks and starting new routes.
• Guide rails removed — use dock rails and wrench-based route visualization instead.

Compatibility

Compatible with both Forge and Neoforged modloaders

What's Changed

• Update to 1.20.1
• Auto-Fishing Barges no longer have their own inventories. It will instead look for the nearest consecutive set of Chest Barges behind it to put items in to. This new change is explained in the Patchouli Guide Book, or when right clicking the Auto-Fishing Barge.

Bug Fixes

• Jittery node text rendering when holding the Tug Route item
• Reworked beacon rendering when holding Tug Route and Loco Route items.
• Fix z-fighting between icon and text when holding the wrench item
• Cleaned up Patchouli guide book.
• Other small audio and visual fixes

Minor stuffs

• Update translation texts for all languages

Notes

• This Update is not compatible with previous versions of the mod, nor is it compatible with worlds created for previous versions of the mod.
• If you open up a world created in 1.19 or earlier, entities and items WILL disappear.

Fix tug/hopper interaction when docked

• fishing barge is now more configurable, and gets 1/2 non-treasure loot by default

• trains and vessels can be configured to ignore some damage sources (create drills and saws by default)

• Add more tooltip info

• fix waterlogged blocks not treated as water

• vessels now have more HP and regen, making them harder to kill (still insta killed by players)

• add config to auto-kill chunkloaders

• trains (incl tug-trains) now try detect when partially chunkloaded and try to wait until fully loaded instead of leaving part of the train behind

• vehicle charger now auto rotates to face the dock

• tugs now have the same GUI as locomotives (button to turn off the engine)

• create compatibility layer (for train contraptions) can now be disabled, use this if LL is broken by a future create update

• collision detection now freezes the train instead of just slowing down/turning off the engine

• trains will attempt to detect when a mob is "pushing it apart" (like fish between cars) and stall until the mob moves away

Fix crash with create minecart couplers
