Patch 1.2.2

Checksum: fb04

Date: May 13th, 2026

Previous Patch: 1.2.1

Government

• Fixed estates with fewer than 1 pop so they no longer receive any power.

Economy

• Changed the minimum threshold for AI attempting to trade for profit to 0.25 profit per TC (down from 0.5), which allows AI to be more aggressive when picking trades.

Society

• Changed characters to die of old age once they reach 100.

Diplomacy

• Fixed the laws enabling the Imperial Armory so they now properly require a preceding law that enables the treasury for the HRE.
• Prevented Junior Partners from being elected as HRE emperor.
• Fixed an issue where Imperial Armories were not properly transferred to the new Emperor and the conversion of the buildings was not updated in the UI.
• Prevented players from unconditionally surrendering in a civil war.

Other

• Gave Trebizond a reduced-requirements path to reform Byzantium, reflecting their Komnenian dynastic claim.
• Changed adding/changing/removing Hellenism religious aspects to cost religious influence (matching Lutheranism), instead of falling through to Inti's stability cost.

Setup

• Fixed a broken dynamic localization key in the Country History for Finnic countries so it now shows the German culture group correctly.
• Moved Padua from the Guelph to the Ghibelline IO at the start, due to the change in its starting ruler (as the country is now aligned with Verona).
• Reviewed and added more unique Town Rights in the setup to urban locations across Europe.
• Added a starting Orthodox Monastery to Kyiv, to round out the design revolving around the Kyiv Pechersk Lavra.

Situations

• Restricted the Balkan League so it can only appear if a Christian country whose capital is in the Balkans owns Constantinople and has at least 100 locations between itself and its subjects.

Disasters

• Changed the second option in the Fate of the Phoenix disaster event "Reformation of the Byzantine Army" to refund 5 Legitimacy.
• Tweaked the "Accept Catholic Delegation" action (accept_catholic_delegation) in the Fate of the Phoenix disaster so that it now also improves relations with the Papal States when the Pope has rivalled Byzantium, as the existing opinion loop had been skipping rivals.
• Fixed the "Fate of the Phoenix" disaster event "Nicaea Reclaimed!" (fate_of_the_phoenix.3) incorrectly referring to the location of Izmit (Nicomedia) instead of the location of Iznik (Nicaea).
• Changed the Fate of the Phoenix starting event so it no longer incorrectly offers Renaissance eligibility as a reward, since the Renaissance always spawns before the disaster ends; it is now offered in the "Decline of the Palaiologos Renaissance" event.
• Fixed John Kantakouzenos never becoming the leader of the Byzantine Succession Crisis, and prevented the disaster from firing while Andronikos III was still alive.

International Organizations

• Fixed the Ilkhanate IO disbanding when all Borjigin claimants had claimed.
• Fixed an unlocalized popup title when accepting "Primas Germaniae" and "Legatus Natus" requests.
• Updated the papal authority game concept description to fit the new mechanics.

Events

• Fixed two Byzantine events that created alliances with subject nations which immediately broke.
• Fixed the Byzantine Kantakouzenos co-emperor event chain failing to trigger. "A Co-Emperor?" (flavor_byz.60) now fires after Andronikos III dies rather than requiring him to be alive, which resolves the cascade block caused by his sickly trait killing him before the event could fire; also updated its description to reflect the post-death narrative. "Rise of John Kantakouzenos" (flavor_byz.32) now triggers when Kantakouzenos is Head of Cabinet instead of gating on Legitimacy > 50, which could be drained below the threshold by unrelated events before the window closed.
• Fixed the "A Hand for Peace" Byzantine event chain (flavor_byz.1200 to flavor_byz.1203) triggering a marriage with the dead Theodora Kantakouzene when she had already died before the event fired.
• Fixed Venice going bankrupt after giving the Crown Jewels loan in the "In Dire Straits" event chain.
• Tweaked the tooltips for the "Byzantine Court Influence" custom tooltips (BYZ_NO_MORE_COURT_EVENTS and BYZ_COURT_EVENTS_WILL_CONTINUE) in the event "Reforming the Corpus Juris Civilis" (flavor_byz.52) so they now explain that these events periodically push the country's Societal Values, which makes the tradeoff between the two options clearer to the player.
• Tweaked the events "New Sparta" (flavor_byz.28) and "Hexamilion Wall" (flavor_byz.38) so they no longer trigger when Byzantium controls more than half the Balkan region, as their flavor text references a Balkans decline that would not apply in that situation.
• Tweaked the events "Restoring Control in Anatolia" (flavor_byz.36) and "Restoring Anatolia Region Cities" (flavor_byz.57) so they can now trigger if the required locations are held by a Pronoia subject, instead of only directly.
• Added different options for the Byzantine Reconquest events of Athens, Nikomedia, Antioch, Jerusalem and Rome, depending on whether the religion of the country is Orthodox, Hellenic, or another one.
• Fixed a duplicate script key for Gemistos Plethon that had been making the event "The Beliefs of Gemistos Plethon" (flavor_byz.1502) fail to trigger correctly. Also tweaked the localization of the first option of the event "Nomon Syngraphe" (flavor_byz.40.a), which had been calling him a 'heretic' even if the player had converted to Hellenism.
• Changed the earliest year at which the Kronborg event of Denmark can fire to 1420.
• Fixed the Restoration of Constantinople modifier having a non-functional global effect.
• Fixed the "Lacking Jewels" modifier not disappearing when Byzantium recovered the Crown Jewels through peaceful territorial transfer.
• Prevented Constantinople from spawning the Renaissance through the event "Palaeologan Renaissance" if it has already spawned.
• Fixed scopes not being properly saved in the event chain "The Iberian Wedding", which had caused effects to not display properly in the tooltips.
• Fixed a localization issue in the event "Expanding the Hofburg" option.
• Fixed the "In Darkest Night" Hellenism event (hellenism_religion.18) firing for Neoplatonist players by adding the missing Monism aspect exclusion, consistent with all other polytheistic Hellenism events.
• Fixed the BYZ crown jewels loan gold amount not being proportional to the crown power penalty.
• Fixed the Byzantine integration flavor events ("flavor_byz.2", "flavor_byz.4", "flavor_byz.5", "flavor_byz.6") being permanently missable when the player created a subject with the relevant provinces before the events fired, by replacing the trigger with another one that checks for ownership of either the country or its subject(s), and removing the "Is Integrating" requirement.
• Added a new event for Trebizond upon conquering Constantinople that unlocks more Bureaucracies for them.
• Fixed Byzantium receiving no notification about the Pawning of the Crown Jewels outcome.
• Fixed the BYZ crown jewels legitimacy debuff not clearing when an ally returned the jewels.
• Fixed an issue where Byzantium would lose access to their DHE when forming Rome.
• Fixed the revolt spawned by the Achaean event "Secession in Epirus" (flavor_ach.7) displaying the placeholder name "orsini_revolt" instead of "Orsini Revolt".
• Fixed broken character scopes override in event chain "A Hand for Peace".
• Fixed broken localization for the Orsini Revolt.
• Fixed the Byzantine event "A Roman Empire?" (flavor_byz.33) firing regardless of culture and awarding cultural bonuses to the wrong culture; the event now only fires if Byzantium's primary culture is Greek or Latin, option A always targets Greek culture and accepts it if the country culture is Latin, while option B now branches its effects based on whether the primary culture is Latin or Greek.

Government

• Changed Nomos Empsychos (Bureaucracy) to grant -30% Crown Power as its negative modifier, and fixed a small issue with calculating Estate Satisfaction impact from Bureaucracy-related modifiers.
• Rebalanced the Prussian "Militarize Country" cabinet action discipline bonus from 0.01 to 0.05 in raw numbers. In practice, that means +5-9% discipline on average, and approximately +17.5% theoretical max.
• Fixed that upon the formation of the Roman Empire from Byzantium, one Bureaucracy Slot was lost, by adding a "Roma Caput Mundi" location modifier granting +1 bureaucracy slot while Rome is the capital.
• Fixed the tooltip description of the "Allowed Wars within Frankokratia" modifier from the "Partitio Terrarum Imperii Romaniae" government reform not mentioning the neighbor requirement for valid war targets.

Economy and Production

• Added a remove_if condition to the Seljuk Mint building so it is automatically demolished when its owner is neither Turkish nor Turkoman culture.
• Fixed the "Imperial Breadbasket" unique town right being practically ungrantable to megalopolises by replacing the max-level granary requirement with a fixed threshold of level 5, since the granary max level scales with development and population and had been far too high for large megalopolises.

Society

• Improved the tooltip for the "Periphora" action (periphora_desc) to clarify that the icon spends about a month in each location along the route, granting art quality bonuses while in transit, and directing players to the Works of Art map mode to track its progress.
• Fixed the Send Emissaries to Rome action description.
• Changed Byzantium so that if it adopts Latin culture, it falls back to existing Greek language location names if those locations do not yet have Latin language translations.
• Made Hellenism Greek/Roman aspect pairs that share a defining modifier (canonization, omen_strength, omens_offered) mutually exclusive, so the player cannot fill both slots with the same effect.
• Changed the modifier gained from "Synod on Local Administration" from the Orthodox Synod to grant only tolerance, and removed its separatism bonus.

Military

• Redesigned the unique units of the Byzantine Varangians to more closely resemble Cataphracts and Legionaries, with one upgradeable unit type per era. However, their numbers continue to increase additively, rather than multiplicatively. With this redesign, the Varangians no longer disappear after becoming upgradeable in the Age of Renaissance, and they interact much better with the content designed to increase their numbers, while also remaining useful across the different ages.
• Removed the initiative bonus from Byzantine cataphract unit types.

Advances

• Adjusted the Roman advance "All Roads Lead to Rome" Road Proximity Cost from -5 to -2, in line with the "Postal Service" advance, as it had been too much of an outlier.

Other

• Changed English Stannary Courts in Cornwall to no longer reduce max control, and instead increase local peasants estate power.
• Modified the scripted geography "Roman Borders", used by the unique CB "Restore Roman Borders", to more closely resemble the stable borders of the Roman Empire in the 2nd century AD. Changes included: removal of Scotland, addition of all missing territory on the Rhine and Danubian borders, and removal of Mesopotamia.
• Added a +1 Government Reform Slot modifier to the "Corpus Juris Civilis" administrative law policy to make it more competitive with the "Byzantine Law" policy.

Icons

• Fixed the icon for the unique "Restore Roman Borders" CB not appearing correctly, which had been due to an incorrect asset naming.

Diplomacy

• Fixed an issue where AI could get stuck planning a war against someone who would call in a third party with whom the aggressor had a truce.

Economy

• Fixed an issue where AI wouldn't upgrade the Seljuk Mint unique building.
• Fixed an issue where AI didn't understand that the army maintenance modifier would also reduce the manpower cost.
• Added extra score for AI to research council hall buildings.
• Added AI score for the Logistic Distance modifier.
• Made AI much more proactive at expanding manpower buildings so they can continue expanding their army as their economy grows.

Military

• Fixed several issues that caused AI to not reassign their armies in sieges to attack nearby weak targets.
• Fixed an issue where AI didn't understand that they had vision in their occupied core territories.
• Fixed an issue where AI could get stuck not recruiting new armies when their existing armies were stuck in foreign territories.
• Fixed an issue where AI would sometimes not disband levies after a war was over.
• Fixed an issue where AI were sometimes not using all armies in a war because they were trying to recover manpower of regular subunits that were prisoners.
• Improved AI at assigning units to siege targets where they would have a valid supply line connection.
• Fixed an issue where AI armies would sometimes travel extremely long distances through enemy countries in order to embark on a ship after the Napoleonic warfare advance had been researched.
• Fixed an issue where AI armies would sometimes be pulled into objectives where two fleets were trying to merge with each other.
• Fixed an issue where AI transports would sometimes get stuck in objectives transporting units that had died.
• Fixed an issue where AI would sometimes hire far too many mercenaries.
• Fixed an issue where AI armies would sometimes move around trying to avoid a disease that they were immune to.

Map Modes

• Changed the Market Access mapmode to use the red-yellow-green colour scheme used for number scales.

Panels

• Changed the Pentarchy panel to no longer require the_pentarchy advance to be researched.

Outliner

• Added a time-left indicator for annexation in the outliner.
• Updated player cards in MP to also display the name of the player's country and their MP score rank.

Other

• Added a new Icon Scaling Quality graphics setting. "Sharp" is a high quality shader that makes all icons appear sharper and less blurry, especially downscaled icons on 1080p displays. The legacy shader remains as the "Smooth" option. Also added "None" (point sampling, cheap).

Other

• Exposed border variables for generation.

Bugfixes

• Localized the Buy/Sell location offer alert title, which previously displayed the raw BUYPROV_ASK_TITLE/SELLPROV_ASK_TITLE key.
• Updated the Militant Faithful event illustration to show clergy instead of peasants.
• Fixed Ragusa so it correctly appears for Italian language in Dubrovnik.
• Fixed a crash when parliaments were abolished.
• Fixed duplicate CBs being listed when you had multiple of the same type.
• Fixed the ctrl-click loophole for advances (CAESAR-66284).
• Fixed not being able to separately sue for peace against a disloyal subject.
• Fixed a crash related to AI handling the focus siege objective.
• Fixed a crash that occurred when opening the log viewer after reloading the game.
• Fixed the God tooltip's omen list so it now shows the omen icon next to each Omen name.
• Fixed Omen modifiers so they now properly show the Omen icon instead of a fallback.
• Fixed a crash related to units' food capacity.
• Fixed a crash on unloading units from a mod or DLC.
• Reduced John Kantakouzenos' life expectancy bonus, as he had been living to be over 100.
• Kept the Byzantine Law when changing to Hellenism.
