Summary (AI)

FluxWerks 5.12 introduces a new error reporting system that captures game snapshots on failure and allows players to send bug reports with logs and saves. Routers and elevators gain enhanced placement options, including building in the air and side-specific controls, with router clusters now functioning as a single unit. The planter now draws limited water from open water tiles, and an invert orbit Y camera option has been added. Several bug fixes address issues with inserters, belts, lighting, and machine behavior. Concrete crafting has been updated to use gravel instead of stone, and the Assembler MK 1 no longer requires a Flux Core, shifting boosting to the MK 2.

Tip: expand all for quick scanning.

Update Notes - Loading a save made in an older version now shows a notification explaining what changed and what needs fixing in your factory.
Planter - Now draws water from open water inside its square. The water level drops as it does so you can't get permanently free moisture.
Invert Orbit Y - Flips the camera's up and down tilt while you hold the orbit button. Turn it on in Settings under Camera.
Router Side Feed - A Router side can now feed a belt passing alongside it. Switch it on per side in the Router's overlay.
Routers - Each side can now be set up before its belt is connected, and keeps its priority and filter when the belt is removed.
Elevators - Now connect straight to a Router placed against either end, with the router's priorities and filters applying to it like any belt.
Line Actions - Upgrade line and demolish line treat a router cluster as one router.
Routing Overlay - Each router side's controls now sit in one small panel with square toggles, and the filter count shows only when a filter is set.
Concrete - Now made from gravel, limestone and water, with gravel replacing stone. Stone already inside a Foundry moves to overflow storage.
Assembler MK 1 - No longer takes a Flux Core. Boosting an assembler now needs the MK 2.
