Update #4 (v0.5.7) Major Update
Replumbed Pipes, Unstalled Buildings and Various Fixes
Official Update #4 introduces the complete Pipes Overhaul with manual connection logic and automatic Pipe Bridges, fixes multiple building stall and propagation bugs, and enables unified blueprint copying with Alt+C.
Key Highlights
Pipes Overhaul: Pipes no longer automatically connect to adjacent pipes when built. To extend a network you need to start or end on an existing pipe tile. Building over a crossing pipe line will now create a Pipe Bridge.
Unified Blueprints: Holding Alt+C will now select both structures and pipes, enabling players to create unified blueprints.
Pipes Mode Tools: Players can now select, move, and copy/paste pipes while in Pipes Mode using standard selection tools, with full Undo support.
Building Stall Fixes: Fixed multiple bugs causing buildings to stop working and propagating, and eliminated Lava leaks through Advanced Filter Walls.

Official Update #3 introduces dynamic Lava terrain destruction across Fluxite, Redsoil, and Strataform blocks, unlocks Critter petting interactions, refines negative-temperature Thermal Buffer physics, and squashes physics-loop edge cases.
