Game update

Patch v12.42

The Sapling · published 2 Mar 2025, 07:10 UTC · build 17563637

All newsPlayers around this dateRead on Steam

Optimizations

  • Turned off a prebuilding system that once saved FPS, but since the new optimizations took more time figuring out which organisms to prebuild; should be make the daily lag spikes less intense
  • For instincts, the game now looking around an animal for trigger if the trigger is 'feeling', speeding up the simulation when there are a lot of animals with feel instincts

Balancing

  • Made the emergence of useful instincts for carnivores more likely
  • Added old meat as a food type to 'aquatic pointy teeth'

Revised species definition

  • Species categorization now also takes into account the parent species: if two identical organisms emerge in different lineages, they will be considered different species. Note: this information is not saved correctly yet.
  • In the species list view, below species it now shows the time since the birth year instead of the time alive, better matching player expectations
  • Fixed forgotten family relations when an alga evolves into a plant
  • Fixed forgotten family relations when a single plants evolves into grass or vice versa

Other

  • Removed subslots below the animal, preventing another cause of the plant duplication bug (thanks Griffvador!)

I often forget to read comments below release notes, so if you have questions or bug reports, feel free to reach out via the Steam forums or [email protected].
