Victoria 3 Hotfix 1.13.7 is now LIVE! - Not for Notes (27th May 2026)

Good day Victorians.

Today we have a larger hotfix for you, with over 100 separate entries, addressing some of the key bugs, AI, balance and more. Notably AI GDP, from our internal tests, should now have returned roughly to 1.12 levels on average.

With these being a select few of the key entries mentioned below; the Kiel Canal now exists and can be built, anarchist successions are less fanatic about seceding, the AI now composes fleets according to desired roles and landlocked countries can now negotiate treaties with countries they cannot ‘reach’. You can read more about the issues below in the full patch notes.

As for our hotfixing plans, we are investigating an issue related to AI getting stuck in naval invasions and hope to get it with you in a smaller hotfix as soon as possible, then a larger hotfix, hopefully similar in size to this one, in a few weeks from now. As for the AI Update we will update you on its expected rough date in a dev diary coming mid-June.

As always, please report any bugs on our bug reporting forums! We have also updated the Known Issues post for 1.13 with any fixed issues.

1.13.7’s checksum is `f369`, and you can check out the full patch notes below.

The following changes have been made to the game compared to 1.13.6:

Features

• Added the Kiel Canal as a constructable canal

Improvements

• You can now negotiate treaties with countries you cannot 'reach', fixing issues such as Spain being unable to complete Hispanoamerica due to not being able to 'reach' Paraguay
• Fixed multiple issues where countries could end up paying very inflated sums for port connection merchant marines (aka busted an embezzlement scheme by the port cartels). We now instead calculate how much each country’s market areas have to purchase from other market areas and attribute a portion of the port connection shipping lane costs proportional to that share to that country as a fee that is paid to the market owner.
• Supply Ships now have proper 3D graphics, using troopship graphics and visually changing over time as you unlock better tech

AI

• The AI now composes fleets according to certain desired roles, such as a main battle fleet or a fleet for raiding/piracy. Different fleets have different ship compositions and sizes, for example main battle fleets tend to get most of the capital ships and to be much larger than other fleets. Fleets will now focus on missions fitting for their composition. Capital ships won't be used for pirating activities.
• Did a major improvement pass on AI fleet mission handling to make it use its fleets in a more logical fashion both during war and peace
• The AI is now better at prioritizing important regions with a high strategic region score for assignment of a stance over less important ones, and should focus its power projection efforts on regions needed to complete certain journal entries, for example
• Fixed a bug where the AI could create invalid templates for some ship classes, resulting in those ship classes never being used
• The AI is now willing to keep some very obsolete ships around if they have a low enough number of ships in the class compared to their desired amount
• The AI will now decommission a limited number of obsolete ships per tick, to avoid overly aggressive mass-disbanding actions
• The AI no longer always fills every utility slot but will make a determination based on utility weight vs number of empty utility slots
• Fixed a bug where the AI was unable to downsize barracks due to attempting to downsize marines that didn't exist.
• Fixed a bug where the AI would be unable to downsize barracks due to disbanding units not flagging their building spending priorities as in need of an update.
• The AI now treats shortages much more seriously when they lack the ability to trade in order to solve them.
• Improved AI fleet and army selection logic for naval invasions and transportation
• The AI now more actively merges small temporary formations in the same location
• Fixed a bug where the AI would abort a naval invasion against an occupied state when taking back the state due to no longer calculating it as a valid target
• The AI will now limit the mission area size of its fleets based on how large they are, with smaller fleets having smaller mission areas
• Fixed a bug where the AI would refuse to defend itself entirely in a war against a much weaker opponent because of incorrectly applied checks intended to keep it from overcommitting against far weaker enemies
• Encouraged the AI to always press the "Promote National Identity" button whenever available in the South American "The \\\[Primary Culture\\] Nation" Journal Entry
• The AI will now wait 100 days after sending a peace deal to send another, giving the player time to propose their own peace deal if the AI's offer isn't to their liking
• Made the Japanese AI more likely to pursue colonial laws if Japan has claims on Korea
• Upon an AI Japan completing Honourable Restoration with either an Imperial or Taikunate victory, Japan will annex a non-player Ezochi

Balance

• Made Anarchist movements less rabid about seceding and encouraged them more towards attempting outright revolution, additionally they will no longer try to secede from nations with less than 5 states altogether
• There is now a 6 month cooldown on changing tolls and strait access settings. Like tariffs and subventions, this cooldown has a grace period of 7 days after changing the setting before the actual cooldown lock is applied, during which you can freely revert to the previous setting.
• Slashed toll rates in half, as they were rather excessive, particularly with single strait controller
• Reduced Merchant Marine cost for port connections and goods transfer treaties to more reasonable levels
• Blockade Efficiency is now calculated as (total blockade strength) / (total blockade resistance of blockaded states) instead of simply blockade strength divided by number of states, meaning that states with tiny resistances won't eat up a large fraction of your blockade strength
• Added a timeout to the Short-Term Tax Cuts Amendment
• Garrisoned armies can now only defend against naval invasions targeting their state or a neighboring state
• Did a major balance pass on utility modules to ensure they all have some use.
• Did a major balance pass on accuracy. Accuracy is now compared against both speed and visibility to determine hit chance, and accuracy modifiers are actually impactful, so capital ships will have a hard time scoring hits on torpedo craft.
• Torpedo craft are now the fastest ship types of their era, rather than the slowest.
• The Ottoman Empire no longer receives 100% Maneuvers in every Diplomatic Play for the duration of the "Tanzimat: Reclaim Syria" Journal Entry, instead it receives extra maneuvers specifically for the war against Egypt in the "Reasserting Our Authority in Syria" Event
• Rebalanced blockade strength and resistance values to make blockades more viable in the mid to late game
• Restricted the headquarters of Witkowitzer Bergbau- und Hüttengewerkschaft to Moravia, and added an Iron Mines potential to this state
• Updated several Journal Entries and Events to account for non-leader Politicians in the National Cast
• Luxembourg now starts the game with all technologies that the Netherlands have access to

• In the Boshin War, the side not in control of Matsumae Domain will now gain a wargoal to annex Ezochi
• Made The Korean Rebellion into an International Situation Journal Entry
• Limited Shinbutsu Bunri completion criteria to starting Japanese Homelands and expanded the tooltip to list them individually

Interface

• The selected mapmode is now the default mapmode which the game will remember and return to after you close panels that change the mapmode. You can also click the globe button next to the mapmode to lock it, which makes that mapmode stay selected even when panels are open that would normally override it.
