Bug fixes:

  • Fixed a bug with gases where buckets were not recognised as containing liquids in certain contexts.
  • Changed the output of the fissile fuel proecessing from spent nuclear waste to standard nuclear waste.
  • The turbine port in the GUI no longer has a solid part.
  • The reactor no longer consumes fuel when it shouldn’t.
  • Fixed an issue where the coolant was no longer functioning correctly.
  • Fixed rendering of the area where builders will construct; it is now well synchronised between the interface and reality, and builders no longer hide each other’s renders.
  • Fixed incorrect counting in the builder simulator for turbines; it now calculates and displays the blades correctly.
  • Dump button disabled for radioactive gases in ports

Tweaks:

  • Default steam processing quantity increased from 250 to 1000 per blade
  • Ports modified; see Features for details.

Features:

  • Added more electromagnetic coils
  • Reactor ports: added a button to clearly distinguish whether the port is for fuel/waste or coolant
  • Reactor and turbine ports now adapt based on their consumption; this feature may not be applied immediately to the ports as it may require the reactor/turbine to be revalidated; clicking the reboot button in the control panel initiates a manual validation or you can wait for the periodic one.
  • Ports containing radioactive gas now emit radiation upon rupture.
