Patch v12.41

The Sapling · published 22 Feb 2025, 12:30 UTC · build 17466908

All newsPlayers around this dateRead on Steam

Changes to the animal juvenile stage

  • The color of the juvenile stage of an animal is now always linked to the adult stage unless you actively change it (so no more accidental brown children)
  • If you add a bodypart in a place where the juvenile stage already has something, and you the remove that thing the juvenile stage has, the result will not be an empty space (thanks Connor McCreesh!)

Fixes for problems related to sexes and sexual reproduction

  • Fixed a timestopping bug when a fallback 3D model for animals is of the wrong sex
  • If an animal loses a sex because of random mutations, but IS the sex that it loses, change sex
  • In the species detail view, when cycling through sexes, the rotating example animal will now show the correct sex (thanks Izaiah Bradford!)
  • Changed how random mutations of the mating system work, to making the emergence of sexual reproduction more likely
  • Finally implemented that calling and making noise make an animal more attractive

Other fixes for timestopping bugs

  • Fixed the animation system not being able to handle blowholes (thanks Connor McCreesh!)
  • Prevented animals that can not make noise from making noise, even if they retain the instinct from their ancestors (thanks Connor McCreesh!)

Fix bodypart positions

  • Improved rotation of all abdomens
  • Slightly adjusted models for the top and side versions of all abdomens, to better connect to the torso
  • Fixed positioning of electric fins during swimming

UI fixes

  • The extermination confirmation modal no longer shows text in front of it
  • The extermination confirmation modal now closes if you close the species detail view, prevent various UI glitches (thanks Izaiah Bradford!)

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].
