Fixing bugs that show up in long running simulations

• Fixed a gamebreaking problem that could emerge with hormone instincts after an animal lost a hormone
  
• Fixed a save file corrupting problem related to saving instincts and diets for the non-default sex
  
• Removed various log messages slowing down the simulation when sped up
  

Balancing plant evolution from algae

• Areas automatically get their nutrients filled up by nearby water, so in these areas plants can evolve without the need for fungi
  
• Added more random variation to the 'starter plant' that evolves from algae
  
• Fixed a problem where the shown statistics of the stilt (mangrove) roots didn't match its statistics in the simulation, leading to plants not growing in 'high moisture, max softness' areas
  

Fixes for the daily challenge

• The daily challenge now uses a less extreme variant of the planet generator, to prevent planets that are too hot or windy for starter organisms
  
• Medium moisture is now the default planet setting (instead of maximum)
  
• Fixed seed selection mechanic, so it should no longer be possible to get the exact same daily challenge two days in a row
  
• Fixed bugs that caused the daily challenge to not always lock for the day after trying
  
• Fixed 'animals that change sex during lifetime' objective not registering
  
• Time is now paused until you click 'let's go'
  

Various changes to the animal editor

• Sleep pattern buttons are now greyed out for the smallest body size, because their lifespans are so short that they will die before they get tired
  
• Dropped support for multiplacement mode (CTRL)
  

Performance optimization

• Hearts to indicate mating now only appear when the animal is somewhat close to the camera
  
• Zzz to indicate sleeping now only appear when the animal is close to the camera
  
• Merged all colored spheres for the flypaper trap into 1 object, so they no longer have a measurable impact on performance (fewer draw calls)
  

Other changes

• Fixed a bug where opening the detail view for multiple species in quick succession caused their names to be mixed up
  

Changed all scenarios to work with the new mechanics in the Scary & Sexy update

• Decreased moisture in 'beach', 'disaster' and 'flower' scenarios, to better reflect what primitive leaves can handle
  
• Changed the milestones of the 'first animal' scenario, as sight is now required to eat
  
• Fixed instincts based on sights actually activating
  
• Made temperature rise in 'greenhouse' scenario less extreme, because evolving heat losing body parts has become harder
  
• Changed the helper notification in the 'greenhouse' scenario to focus on skin and eggs (instead of body parts) to beat the heat
  
• Fixed plants with various seed types not triggering the final 'flower' scenario objective
  
• Finally removed 'ice age' scenario
  
• Added icon for 'swamp' scenario
  

Further tweaks to the scenarios

• Made the sea in the 'first animal' scenario deeper, so you can use the just introduced plankton in a larger area
  
• Hovering an organism over terrain where nothing is allowed (for example, because it outside the play area) will no longer show terrain stats
  
• You can no longer place organisms outside the play area
  
• Made scenario clouds less bright, so the bloom effect (to highlight bioluminescence) in the evening is less extreme
  
• The clouds in the greenhouse scenario are now a little higher, so they don't block the view of the plants
  
• Made pollination occur also if the nectar eaters choose to eat other food (making the 'flower' level way easier)
  
• Made 'completionist' achievement more dynamic, so it does not matter how many scenarios I add or delete
  

Tweaking mouth part stats

• Revised the mouth part evolution tree so you can see some air breathing mouths without using the arrow buttons
  
• The 'attractive mandibles' now evolve from the 'larger mandibles'
  
• Made the 'nectar feeder' and 'nectar feeder with external parts' much better at extracting energy from nectar
  
• Decreased the hitbox size for the 'semi aquatic plant eater'
  

Other fixes

• Various fixes to remove incorrect family tree lines in the plant and animal editors
  
• Eggs that are not the default land/water hybrid eggs now also have hover labels telling you what species is inside (instead of FPS eating errors in the log file)
  
• Fixed the archive button
  
• Made sure the leave buttons (to main menu or desktop) continue to work, even if the autosave right before it fails
  

Save file format 10

• The secondary color of juvenile stages and other sexes

• 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)

• Only show the 'display' option if the animal actually has something to display (that is, bodyparts that have a 'folded' state)
  
• Polished positioning of the color pickers
  
• The lower part of the range indicators in the color pickers now also shows being hovered
  
• Added labels to the 'see alga', 'see plant' and 'see animal' instinct condition parameters

• Fixed mixing up fungus species after saving and loading
  
• Fixed super old age of fungi after saving and loading
  

Fixes related to ocean depth
