Update #3 (v0.5.6) Major Update

Happier Critters, Hungrier Lava & Assorted Factory Improvements

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.

Key Highlights

  • Hungrier Lava Mechanics: Lava now actively melts and destroys Fluxite, Redsoil, and Strataform terrain tiles upon physical contact. Encasing lava channels in Basalt or Foundations is now mandatory.
  • Critter Petting & Interaction: Players can now directly pet and calm local Critters, preventing agitation around sensitive conveyor lines.
  • Thermal Buffer Sub-Zero Physics: Introduced responsive thermodynamic interactions when Thermal Buffers operate under negative temperatures.
  • General Performance & QoL: Optimized large-scale factory physics and eliminated edge-case memory spikes during late-game drone sweeps.

Detailed Changelog

  • Added erosion collision tests between uncontained Lava and exotic terrain types (Fluxite, Redsoil, Strataform).
  • Enabled cursor petting interaction on all roaming Critters.
  • Updated Thermal Buffer state transitions when handling negative cryogenic temperatures.
  • Fixed collision glitches when placing Launchers adjacent to multi-tier Shaker chutes.
  • Enhanced save file integrity checks against legacy mod data structures.
