Patch v12.31

Save file format 10


Loading save file version 9 is still supported, but if you click 'save' now the game will also remember:

  • The secondary color of juvenile stages and other sexes
  • Traits specific to juvenile stages and other sexes
  • Instinct and diet options specific to juvenile stage and other sexes
  • The birth locations of species
  • In the species detail view, not only which species your species is eating, but also in the form of what food type (eggs? fresh meat? etc)
  • Fungus organism caps
  • Fungus mutation chance
  • Energy collected by living plants and animals (to increase the chance they live through the night)


Fixes and changes related to saving and loading


  • Fixed a problem where plants died after saving and loading: the game incorrectly thought all plants were in an environment too wet and without nutrients
  • Added an autosave when exiting the game
  • Removed needless logging from the save/load process, making it much faster
  • In the savegame list view, sandbox saves now show the sandbox icon
  • You can now save scenarios before completing the first objective without the game crashing
  • When loading a scenario, night cycle periods are now set correclty
  • When loading a scenario, allowed alga and plant colors are now set correctly
  • Fixed a crash when exterminating populous species immediately after loading a save
  • Added save file versioning explanation to the load view


Working on the daily challenge


  • There is now a main objective view before you start, including an explanation you get only 1 attempt
  • Starting the daily challenge now only 'counts' AFTER you click 'let's go' in this new objective view
  • Added events like meteorites to the objective description
  • Fixed time stopping bug when the meteorite hits the world
  • Removed options to the retry from an autosave (which didn't exist anyway) if you fail


Tweaking the manual mutation mechanics and UI


  • Removed the option to mutate organisms that didn't reproduce yet (but just survived long enough) because this messed with the species counts... I think it contributed to the negative population size problem
  • Removed 'mutate' from the dropdown menus in the sandbox, as mutating doesn't make sense in this game mode
  • Removed the 'mutate' button from the organism detail views
  • Added a mutate icon to the species detail view, but only when mutating is possible (so not in the sandbox)


Fixes for the juvenile stage in the animal editor


  • Fixed bodypart hitbox sizes for juveniles
  • Fixed a crash that sometimes happened when resizing body parts of a juvenile animal


Mouth statistics balancing


  • Added grass and fresh meat energy for 'semi aquatic plant eater'
