A completely new cladogram view


I've replaced the old cladogram view, because playtesting quite consistently showed that nobody was using it. The game is now using a completely new chronogram approach as can be seen in both Species ALRE and The Bibites. It should give a much better 'zoomed out' overview of which species branched off from which one at what point in time. Even though previous changes to speciation drastically reduced the number of species, the trees in this new cladogram/chronogram can grow quite large, so this view has been heavily optimized.

Perhaps surprisingly, by far the hardest part were the resizable scrollbars that allow you to navigate large trees. I believe most issues have been fixed, but they sometimes still revert (making the view go left instead of right) for reasons I do not understand yet.

UI mutation fixes

  • Fixed the animal mutation view no longer always showing the nr of plant species as 25 (thanks, Jotbe!)
  • When selecting mutation rates, the UI now shows the correct max value of 35% (thanks, generaldisbelief, JupiterHater!)
  • When closing and reopening the mutation chance pickers, they now continue showing the correct value

Introducing the next version save file format

  • Fixed body stance not being saved correctly for juveniles and sex B-F (thanks, AncientRelic!)
  • Fixed speciation threshold not being saved correctly, which caused saving+loading to delay speciation

Misc

  • Made the heart icon to indicate mating less frequent at high timespeed (thanks, Jupiter Hater!)
  • In the planet editor, switching to the rotating planet and back to the map now only shows the drawing circle when needed (thanks, TheSpaceCore69!)

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