Simulation fixes

  • Prevented another way the sessile feet could evolve to be on the side. This bug causes numerous problems, like plants multiplying, corrupt saves and missing models in the species list view (thanks azul1462, TaterTot, MisterLiteralRandomGuy!) EDIT: hmm I just encountered this problem again, still not fully fixed
  • Fixed sessile animal babies moving around (thanks ultraneongodpet, Jupiter Hater!)

Working on new limb body parts

  • Added a new gliding limb as intermediary step between insect limbs and insect wings
  • Remodeled the pterodactyl wings to be more impressive and closer to reality
  • Added top and back models for the exisitng gas bag body part
  • Added second larger gas bag body part
  • Fixed forcipule bodypart (was pointing the wrong way)
  • Improved the hitboxes for various limbs, so it's easier to (re)move them

Terrain editor fixes

  • When hovering multiple continents, only the smallest one now lights up (thanks Tatertot, Col. caboose!)
  • When hovering a contintent with a small map size in the planet editor, it now highlights correctly
  • When drawing new land mid simulation with a small map size, it now shows up at the correct position, with a size matching the brush size
  • Drawing outside of the map mid simulation no longer causes terrain in the exact middle
  • When toggling rings, the stats are now always updated correctly
  • Fixed the black maps that sometimes showed when editing terrain mid simulation
  • Fixed drawing mid simulation no longer being possible after changing the elevation of a continent

Soil statistic fixes

  • Added nutrients to the soil statistics in the world, including for the first time the option to paint nutrients
  • Got the wild fire risk map to work mid simulation
  • Fixed the wrong slider showing when looking at the wildfire risk in the planet editor
  • Your changes to manual statistics in the planet editor are now actually used in the simulation (thanks azul1462!)
  • You no longer lose all your manual statistic changes in the planet editor when switching to the planet or disaster tabs
  • Fixed softness/rockiness being inverted in some views
  • Fixed polar regions often being black instead of white when looking at the climate zones mid simulation
  • Fixed volcano eruption not updating the soil stats (thanks lin!)

Improving terrain editor audio

  • In the planet editor, the sound effects when editing terrain now match your cursor movements more closely.
  • The terrain editing sound effects now stop less abruptly

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].
