Summary (AI)

Europa Universalis V patch 1.3.6 introduces population details to area tooltips and improves the Traditional Economy by allowing larger rural resource operations and removing building efficiency penalties. Estate satisfaction penalties from individualism and religious tolerance have been reduced, while several fixes address issues with HRE elections, union mechanics, and rebel faction behavior. The patch also rebalances AI behavior related to conquest and diplomacy, updates cabinet traits, fort and mercenary mechanics, and corrects various event and UI inconsistencies. Notable improvements include refined annexation processes, enhanced tooltip clarity, and stability fixes for mercenary recruitment and diplomatic actions.

Tip: expand all for quick scanning.

HRE election no longer stalls indefinitely when an ineligible candidate (e.g. extraterritorial republics like the Hanseatic League) accumulates majority of elector votes.
Junior union members no longer get caught in a Negotiate Succession Law opinion spiral through the heir-selection (succession law) path.
Child union leader no longer renders an empty Union panel during a regency.
The Charismatic Orator cabinet trait now correctly erodes noble estate satisfaction as its downside. The intended penalty was previously a no-op, making the trait a free bonus instead of the designed trade-off between parliamentary appeal and noble deference.
Expired loans no longer drift into negative remaining interest when the "we can repay a loan" notification is suppressed.
Improved text for "Challenge Circle Leadership" action and resulting event.
Annexation is no longer stalled due to revolt wars in other subjects.
The trust impact for inviting countries to an Independent Movement is no longer multiplied by 4.
The Scaligeri War peace treaty now correctly evaluates Milan's demands, a copy-paste error had them reading Florence's war variables instead, which could produce wrong demand values or availability conditions during peace negotiations.
Embarked armies now suffer lack-of-food attrition.
Hired mercenaries no longer stall forever when their spawn location is occupied.
Independence war goals now correctly target the subject's capital and display the subject's name in the "Liberate \[Country]" label, a broken scope reference had silently pointed the entire war goal at the overlord instead.
Defeating a nationalist or patriots revolt that had taken all of your territory now correctly returns your country to its normal form instead of leaving it permanently army-based.
Province-claim casus belli is no longer lost at civil-war start.
Patrol the Seas fleets no longer leave port to chase a repair port outside their naval range.
Delisting a mercenary navy carrying troops no longer drowns the embarked armies.
Populated the mercenary pool at game start.
Extraterritorial countries can no longer lead an HRE Imperial Circle.
Fort ZoC shelter from local attrition now extends to direct subjects and overlords.
Changed mercenary availability to draw from population, with per-arm scaling.
Pruned dead members from the dynasty available-members cache.
Restored Dynastic Names for the Habsburg, von Wittelsbach, and von Hohenzollern dynasties.
Expanded the name list for male and female names used by the Kantakouzenos, Komnenos, and Palaiologos dynasties.
Guelphs and Ghibellines: Made being a member of the Guelphs a negative factor in imperial elections, so AI countries now consider it a reason against selecting them.
Italian Wars: The action "Challenge League Leadership" in the Italian Leagues now correctly shows the right title "Challenge..." instead of "Seized..."
Hussite Wars: The outcome of Hussite Victory no longer penalizes allies and subjects of Bohemia (e.g. Poland!).
Italian Wars: Countries can no longer rejoin a war via "Intervene in a War" if they have a truce with the target country.
Reworked the "League Demands Autonomy!" event (flavor_fra.2033) to fire an invitation event (flavor_fra.2035) to League of Public Weal members instead of automatically forcing them into the war against France.
Expanded the Venetian government reforms "Magistrato alla Sanità" with Global Life Expectancy +3 and Population Growth +0.025%, and the "Provveditori ai Beni Inculti" with +10% Global Max RGO Size.
Appanage and other subject types with allow_subjects can now create Historical Subjects.
Reworked temporary Diplomatic Annexation Efficiency bonuses to instead boost monthly annexation speed, so their benefit is no longer lost on long annexations.
Restored access to the "Early Iberian Caravels" advance for all Iberian countries, including Portugal and Castile.
AI now caps parallel colonial charters at 2/4/6 by country rank (duchy/kingdom/empire).
Portugal no longer rivals England (and vice versa) at game start.
AI now uses uncapped antagonism values when calculating Peace Offers, allowing them to take more land if the initial antagonism is negative.
Updated AI Conquer Desire scoring to soften the distance gate, dampen for dynastic partners, and skip own subjects.
Moderate military disadvantages now weigh more heavily against AI expansion — a 2:1 or 3:1 strength gap now noticeably dampens aggression where the old formula barely reacted.
AI Conquer Desire now rewards regional and area consolidation — completing the last few tiles of an area you mostly own now scores higher than scattering into unrelated neighbors.
The AI now values territories it holds an active casus belli against more aggressively when planning expansion, making it more likely to follow through on legitimate claims.
AI now hires naval mercenaries when losing a naval war.
Diplomatic action buttons now show the accept/decline icon for multi-stage country interactions.
The HRE emperor (and other IO leaders who always defend another country) can no longer be selected as a co-belligerent call-in, since they are always co-belligerent anyway.
The global population growth modifier now shows up to 3 decimal places, so very small modifiers display their actual values instead of 0%.
When hovering over the outliner trade income value, the listed trades now show a further breakdown with the detail of each trade.
The "Elevate Country in Circle" action no longer shows a blank confirmation message.
Trait loss now shows a notification.
Removed the scroll from the Imperial Circle Actions panel.
When the cabinet action for Changing Societal Values finishes, the message now indicates reasons why it stopped pushing towards the Societal Value.
Very small countries can no longer generate unrealistically high threat scores due to near-zero value normalization, preventing tiny neighbors from being incorrectly flagged as Alarmed.
Stopped generating city graphics early when they have no preview mesh (i.e. a castle).
Dismissing or delisting a mercenary from the Hire Mercenaries panel no longer drowns embarked armies.
