  8. Load screen has an indicator to show how to start using cloud saves. (Goes away after 5 appearances, or after the user clicks on the button.).


  1. Oil Well now dumps and takes damage from incorrect liquids, rather than storing them and getting blocked.
  2. Oil Well now has better logic to keep it from getting stuck pumping if something goes wrong with it.
  3. Fix Petroleum Generators from getting stuck if they’re supplied with mixed fuels, now they seamlessly change over.

Systems and Simulation

  1. Fixed partial heat transfer increasing energy and flaking fountain.
  2. Fixed Fish Feeder flaking.
  3. Fixed both Heavi-Watt Wire Bridges from flaking and doubling mass on melt.
  4. One cell buildings should no longer flake when melting.
  5. Clarified Petroleum Generator description.
  6. Fixed artifacts not being generated if they are the last artifact of a tier.
  7. Fixed power networks sometimes becoming overloaded when they are exactly at their power limit.

UI and Text

  1. Fixed scaling issues for anims in the UI (notably, Duplicant portraits at high resolutions).
  2. "More Info" on the error includes the actual error message in addition to the stack trace.
  3. Enlarged the clickable area to close message notifications so that it’s easier to dismiss them.

  4. Replace ArrayRefs in ScenePartitioner with HashSet for 5% frametime savings.
  5. Small optimization to Symbol Override system ~.5% frametime by removing unnecessary data copying.

  8. Optimized the way Dupes think about toilets. Saves about 4% of frametime for colonies with many Dupes.
  9. Further optimizations to toilet selection. Can have huge benefits for large numbers of Dupes and toilets: ~20% of the frame on a Dupe stress-test colony.

Filesystem and Backend

  1. When deleting a save, now tries to remove the png as well.

Final patch from the preview branch

  1. Added a cloud/local button on the new game screen so it’s more clear what the current setting is.
  2. "Back" is now localizable on the Load Game screen.
  3. Fix formatting of the "Growth Halted" status item so it’s less confusing.
  4. Can no longer create colonies with duplicate names (old colonies with duplicate names will still work, but will get migrated to/from cloud together).
  5. Fix error migrating colonies with duplicate names.
  6. Don’t delete the autosaves for a different colony with duplicate names, only for the current colony.
  7. Hide the "Cloud saves tutorial" bouncer if cloud saves are not available.
