Create: Fluid

 ## [2.1.6] - 2026-09-13

### Added

- Creative Fluid Tanks and Copper Sinks with infinite water enabled now correctly advertise an unlimited fluid supply to the fluid logistics network.
- Added block loot and shovel mining tags for Quicksand.

### Changed

- Improved Logistics Junction selection interactions:
- Sneaking now skips target selection and allows normal placement.
- Creative-mode players can now break selectable targets normally.
- Improved particle spread for vertically oriented Fluid Atomizers.
- Corrected the fluid-container state handling of Powder Snow Buckets and Quicksand Buckets so they become empty buckets after an executed drain.
- Copper Sinks now play the vanilla bucket-fill sound when filling a water bucket.
- Can Fillers now correctly recognize infinite fluid sources and plan requests according to the capacity of an individual package.

### Fixed

- Fixed Mechanical Pipettes losing their client-side interaction targets after leaving and rejoining a world.
- Client target reconstruction now preserves server-selected positions while target chunks are still synchronizing.
- Target edits are detected by complete NBT contents instead of only by target-list size.
- Server-side target validation remains strict and is not weakened by the client rendering fallback.
- Fixed fluid-fed Blaze Burners receiving only 10,000 ticks from 1,000 mB of lava.
- Lava now matches Create's lava bucket fuel value of 20,000 ticks, or 1,000 seconds at 20 TPS.
- Burner fuel state is explicitly notified after fluid insertion so it persists and synchronizes correctly.
- Fixed item and fluid duplication when a Logistics Junction unpacked a Brass Box, cardboard package, or Copper Can.
- Unpacking now performs a complete simulation before committing changes.
- A failed commit rolls back only the contents inserted by the current transaction.
- If a non-transactional third-party handler cannot be rolled back, the source package is consumed to prevent duplication.
- Fixed Can Fillers settling only Factory Gauge promises while ignoring network promises from Stock Links.
- Fluid autocrafting requests no longer repeat indefinitely because of unsettled promises.
- Can Fillers no longer repeatedly send Copper Cans to themselves when the network lacks enough fluid to complete a request.
- Fixed block entity rendering crashes caused by registering the `fluid_interface_drain` partial model too late.
- This covers the drain rendering paths used by Fluid Interfaces, Smart Fluid Interfaces, and Communicating Vessels.
- Fluid Interfaces and Smart Fluid Interfaces now support waterlogging and are no longer displaced by flowing water.
- Fixed duplicate shaft rendering on Logistics Junctions.
- Fixed Mechanical Arms failing to recognize Can Fillers as packaging interaction points.
- Added missing pickaxe mining tags for Can Fillers, Logistics Junctions, and Smart Repackagers.

### Compatibility

- Minecraft `1.21.1`
- NeoForge `21.1.219+`
- Create `6.0.8+`
- Development and runtime validation were performed with Create `6.0.11`.

### Validation

- Added an opt-in NeoForge GameTest regression suite for Mechanical Pipette target restoration, cauldron fluid exchange, Blaze Burner lava fuel timing, and the two-pipette lava transfer chain.
- All four regression tests pass against the local Create `6.0.11` development runtime.
