Better Looking Worlds

  • Both from the surface and from orbit, planets received a facelift (or continent lift).  We've introduced many new islands, continents, and landmasses used by the planet generation system.  We've also improved our material system to improve shorelines, add more color, and add more detail to planets.


  • Fixed various bugs that caused autoskip not to, you know, bloody auto skip!
  • Fixed an issue where Prototype Hyperdrive said it needed Promethion, but it actually needed Anti-matter (it now requires Promethion correctly).
  • Fixed an issue where the Thullium Hull Reinforcement required Durantium.
  • Fixed an issue where the United Earth faction wasn't using the correct Map Color, UI Color or Appearance.
  • Fixed an issue where some events weren't changing population correctly (thanks to Old Spider for the fix!)
  • Fixed a crash when using debug commands to trigger events out of order.
  • Fixed a typo in the Nanite Fabricator description.
  • Fixed the Illegal Cloning event Pragmatic growth bonus.
  • Fixed the Illegal Cloning event Malevolent Population bonus.
  • Fixed the UP Resolution War Fine to have a duration.
  • Fixed the Mowling duplicate intro screen text.
  • Updated the Cultural Beacon description to state that it allows the training of celebrities.
  • Fixed an issue keeping the Nanite Transmitter Complex from being buildable.
  • Fixed an issue where Space Monsters might not appear on some events if you don't have Crusade installed.
  • Fixed an issue where players wouldn't receive credits in trades
  • Fixed a stuck turn if you continued playing after winning the game.

  • Made Galaxy Destruction faster (most noticeable when you go to load a save from within a game).


  • Fixed typos.
