Victoria 3 1.15.1 Hotfix Notes (11th November 2026)

Happy Wednesday Victorians!

Today's hotfix brings the first set of bugfixes, balancing and improvements since the release of Update 1.15 and State and Revolution! Some highlights include: Regime Change now allowing the target country to adopt normally unavailable laws as long as the country doing the regime change has those laws enacted, Copper being both consumed less and being more available, more AI improvements and more!

As always, please report any bugs on our bug reporting forums! We have also updated the Known Issues post for 1.15 with any fixed issues.

Otherwise, check out the full patch notes below. Checksum is `f843`.

The following changes have been made to the game compared to 1.15.0:

Improvements​

• Regime Change now allows the target country to adopt normally unavailable laws such as Council Republic so long as the country imposing the law change has that particular law enacted
• Regime Change will now establish friendly relations with the target country. Any IGs that were put into power by the regime change will join a lobby in favor of the imposing country, while any IGs forced out of power will join a lobby opposing that country.
• Revoking Favoritism character interaction can now only be taken once every 5 years. Appoint Favorite character interaction can now be taken once every 6 months.
• A White victory in the Whites and Reds Journal Entry guarantees Russia cannot decrease the autonomy of Congress Poland or use the Install Favored Ruler Overlord Action for 10 years
• "Cause Without a Rebel" event now only targets agitators whose movement has marginal support

AI​

• The AI now correctly counts the wages of new jobs as a cost when picking production methods, and counts only workers who are actually laid off as wage savings
• The AI now properly considers goods output and input multipliers when comparing production methods
• Fixed a bug that made the AI avoid production methods that move jobs to more skilled workers even when it had qualified pops to fill the new jobs. This especially impacted its ability to use electrical PMs.
• The AI's minimum mobilization target is now capped by the amount of military power the enemy can potentially bring to bear, so Great Britain should no longer mobilize half its army to put down a native uprising, for example
• The AI now puts more priority on advanced industrial goods such as radios, telephones and oil when it makes sense to do so
• The AI now scores labor-saving methods higher in states with a lack of workforce
• The AI will no longer subsidize profitable buildings or buildings that it does not consider as genuinely necessary for its economy
• The AI now budgets for mobilization options according to the severity of the war, and will avoid using expensive options for minor conflicts
• Fixed an issue with British and Russian AI weights in Persia applying in an incorrect way
• The AI now makes use of the anchorage PM for ports when it has no need of Merchant Marine
• Added a grace period and an alert before the AI withdraws from a treaty with the player

Balance​

• Made a pass over Copper availability. It's now more available and also less consumed by industries. This should make it a lot better already, but we keep monitoring feedback on this.
• Cossack Hosts are less effective at pulling migrants into their states
• Capitalists are now drawn to the Armed Forces when their Financial District or Company Headquarters owns military industry
• Updated the starting tech for Waterboersland and Philippolis

Art​

• The Russian building set now also appears in the Ural, East Karelia, and Kola Peninsula geographical region (State & Revolution)
• Properly hooked in the new icons for Prestige Goods (State & Revolution)
• Rosa Luxemburg now wears period-appropriate clothes and a hat instead of Russian court dress

Audio​

• The State and Revolution main menu theme now plays for players who own the immersion pack (State & Revolution)
• The Melodies for the Masses Music Pack's title track "The People" can now be selected in the music player

Content​

• Additional character events for Favorites

Interface​

• Added a World Market Hub filter to the market panel's Trade tab, World Market Hub map markers now show their name, owner, trade capacity and market area, and the Sea Region panel lists the hubs connecting through it.
• Production method change tooltips now include goods output and input multipliers in their predicted production and consumption
• Fixed a bug where tooltips and panels for Fronts connected to an invasion could count defending armies twice
• Fixed a bug where tooltips and panels for Fronts displayed different number of units present due to sometimes including units without any manpower
• The market access tooltip shows the market owner's flag and no longer repeats its value
• The outliner now shows when a fleet is being repaired or is defeated
• The goods panel tabs now show a prestige good's own orders, producers and prices instead of its base good's
• Law commitments in treaties can now be clicked to open the law
• Added State and Revolution badges in the UI to Great Game content now that multi-DLC badges are supported
• The historical outcome marker in journal entries no longer covers the outcome text
• Enforced treaty binding periods no longer run out of their frame while the war goes on
• Raise conscripts and mobilize labels no longer overlap their icons in longer languages
• The outliner journal entry header no longer overlaps its counter in longer languages
• Fixed a bug where the Conscript number overlaps the other Military stats on the Mobilization tab in the Military and Army panels

Performance​

• Improved performance when selecting multiple armies

Modding​

• Added a new can_secede_during_revolution flag for movement (default: no)

Bugfixes​

• Personal Unions can no longer appoint favorites
• Fixed a bug where a fleet attempting to merge with another fleet it cannot reach would make the fleet stuck trying to merge forever and ever until it can
• Fixed a bug where exiled armies were not allowed to move to a port to be transported if they were not in a province with a port
• Fixed a bug where you could get prestige below 0
• Regime Change is no longer available against countries where no law change would take place
• A revolutionary movement no longer turns into a secession when another movement overtakes its revolution by default
• Modifiers applied via Ukases are now properly removed when the Emperor and Autocrat Journal Entry fails
• The Synod of Polotsk event now properly applies the Crypto-Uniate Communities modifier
• Fixed a bug where Interest Groups disappeared completely from the Government panel after changing laws to Autocracy until an in-game week passed
• Fixed an issue that caused paused construction sectors to still be included in some private investment considerations
• Congress Poland can no longer side with Polish Secessions via the regular diplomatic play mechanics if the Whites are dominant
• Subjects will now follow the overlord to become "on the fence" in diplomatic plays
• Fixed a bug where wars could end early when its Conquer State war goal's holder gained a claim on that state, instead of the war goal becoming Return State
• Subjects can now properly join a same-culture secession against their overlord under the same conditions that they can normally rebel
• Added a toast notifying players when a nationality creates an autonomous state in Russia during the Provisional Government
• Fixed a bug where a decree in subjects lands would remain after losing Vassalization III principle, you also could not manually cancel them
• Children no longer clip through their clothes when they would otherwise be overweight
• Communist flag for United Baltic Governorates when formed from Estonia now appears as intended
• Added missing localization for toast about war breaking out
