by PDX-Loke Greetings everyone, Another patch has been completed, wrapped up, and sent for distribution via your your platform of choice. 4.0.15 should now be available on Steam, and GOG and MS store following shortly. Please find the patch notes below.

Stellaris 4.0.15 Patch

• When a species is modified the new version will now automatically be the default
• Updated Job Efficiency modifiers from Purity, Cloning and Mutation traditions to only affect Organic pops (this includes lithoids)
• Technologies that when researched upset Fallen Empires are now marked as dangerous.
• Limiting the pop housing multiplier to never completely remove the housing needs. Added the define MIN_MODIFIER_MULT that allows modders to tweak the minimum value as needed.
• The Synthetic Fertility origin has received a little bit of love. The situation now shows the months until the end of the situation, and the situation progress is now representative of the actual steady progress. At the end of the situation the exact pops amount is now also uploaded, instead of losing the last few.

• Wilderness Empires that finish the Domination Tradition Tree now have access to the Hegemony Federation Type
• The Psionic Storm is slightly less mystical as it should no longer convert black holes back into real stars, The Great Wound is too mighty for a mere storm.
• You can no longer smuggle out Biomass from Wilderness Empires
• Technologies that grant Fallen Empire buildings now grant +1 to the empire limit of that building. In addition, these technologies are now repeatable. The technologies that unlock the upgraded versions of the Fallen Empire buildings increase the empire limit of the base version, but the upgraded buildings count towards the limit.
• Having the Cosmogenesis Perk that grants access to Fallen Empire Buildings multiplies your empire limit for those buildings by 3.
• Fallen Empire buildings that Fallen Empires start with are generally slightly more powerful than those that can be constructed and do not count towards empire limits.
• Effects that grant access to Fallen Empire buildings, e.g. dumpster diving in minor artifacts, now grant you one level of the relevant technology.
• Gestalt empires can now access Fallen Empire trade buildings
• Rare Fallen Empire technologies are now correctly affected by all modifiers to draw weight of rare technologies.
• The draw chance for Fallen Empire buildings from Enigmatic Engineering has been decreased from 3.75% to 1.5%.
• There is now no limit to the number of times you can research Fallen Empire buildings with Enigmatic Engineering.
• Removed technology requirements for basic City District Specializations. An upgraded capital building is still required for the second Specialization.

• The Awakened Control Fragment will no longer denounce itself in the Galcom when it comes to picking a side in the War in Heaven
• The Wilderness will no longer be taunted by the Strip Mine Planet decision, it is now hidden.
• Refactored Tzynn Tithe to use the new pop system and being much prettier script
• You can no longer raid the poor crisis factions for their pops. They aren't supposed to be real!
• Storm Chasers now properly have no rare crystal upkeep on their Storm Attraction Centers
• Pirates will no longer decide to set up shop in Leviathan controlled systems.
• The pirate event will now check that it has a system it can spawn pirates in before firing. So now if you want to ensure that you don't have pirates you have to build outposts everywhere, which kinda makes sense...
• Updated the Esteemed Quartermaster trait to mention 100 Soldiers
• Promising young officers will no longer show up when piloting civilian craft. Also updated the event to change picture if the officer was on a starbase or a biological ship.
• Deep Space Citadel will no longer display duplicated models in certain situations.
• Added missing descriptions to Space Fauna tab in Fleet Management.
• Added requirement of >=2500 Pops to Megastructure builder tooltip for Grand Archive.
• Fix Grand Archive thinking it's still destroyed after being rebuilt
• Fixed leaders getting the wrong number of trait selections.
• Cloned leaders now copy pending trait selections from the original.
• Fixed Xeno-Compatibility growth calculation using the wrong number of pops.
• Aligned Genetic Memory tooltip with effects
• Fix missing description for the coordinator job
• Corrected job information for Justice Complex and Ziggurat of Justice buildings.
• Fixed the Metallurgical Research Lab, Distributed Design Center, Data-Driven Theorem Facility and Military Academy not providing some bonuses for gestalt empires.
• Fixed Automation buildings not having any upkeep on habitats
• Fix Robot species with negative traits costs sum declining
• Uplifted presapients now correctly enter the Civilian stratum
• The Nanite Interdictor can no longer equip both cruiser and battleship reactors
• Fixed Job Efficiency modifiers for species types not working in some cases
• Fix Synaptic Lathe view not always updating properly
• Colonizing planets will now take damage again from bombardment
• Abandoning and resettling the same colony multiple times will no longer grant you multiple Planetary Root Bundles.
• Vaults of Knowledge now once again tracks your leaders destiny traits, and will no longer reset if you lose your capital.
• Regular colonies will be destroyed of all the pop groups are already dead. Previously a 0 sized sapient pop group would have prevented the destruction of the colony and some other events (like an ongoing colonization) could have introduced some new pops into the planet - leading to a colony, that just would not die.
• Idle gestalt drones now demote much faster.
• Colony Auto-Designation no longer thinks that job producing buildings like Temples are 100x as awesome as it should consider them.
• Adopting Genesis Guides mid game will no longer prevent you from colonizing planets until you researched any new ship tech.
• Ecclesiastical Center colony designation now has proper tooltip
• Gestalt Lost Colony Empires will no longer be trying to create buildings they can't use.
• The planet view's portrait is now correctly displayed after changing planet class
• Common Ground federation allies now start with Planetary Administration building.

• Significant adjustments to AI priorities.
• The AI can now sell Energy for Trade.
• The AI is more willing to build Districts, and double down on District Specializations. (Or similar Specializations, like Physics and General Research might go together.)
• The AI will no longer feel content with itself if it has 10000 Pops.
• Job Output modifiers for AIs on Captain difficulty and higher have been changed to Workforce bonuses. Their jobs will now consume more resources than before, but the difficulty bonus now affects all outputs of their jobs, not just resources.
• AI (and Planetary Automation) will now prefer to build inside District Specializations than in free building slots.

• Add tooltips to Focus Card rewards
• Fix an empty cost string in the Change Focus confirm popup
• Add a pulsing glow to the district pip about to be built when hovering the build district button

• Fixed an OOS where a research agreement would go through on the client but not on the host, leading to random desync
• Fixed another OOS at reconnect due to espionage modifiers from the Active Reconnaissance fleet order

• Changed leader add_trait to have "trait", "consume_selection" and "show_message" parameters; removed add_trait_no_notify.
• Fixed traits override for clone_leader.
• Added more info about traits to create_leader and clone_leader documentation.
• Most Pop effects that use amounts can now have a randomized range
• add_building will no longer add districts that can't be built.
• Add country modifiers to District Specialization types
• District Specializations can now be limited per planet and/or empire, like buildings
• We now have an add_variable effect to complement the subtract_variable effect
• Add ai_priority field to District Specializations so AI and Planet Automation know better where to build structures

• Bugfix: Wilderness Empires will no longer destroy themselves when spending biomass
• Bugfix: Virtuality will not delete unemployed pops on colonization
• Fix numerous instances of OOS issues
• Savegame transfer goes brrr
