Ahoy Victorians!

Hotfix 1.13.5 has just released, featuring some key fixes and improvements to the experience of 1.13, including making the AI less gung-ho about supply ships and ruining their economy in the process, fixing MAPI not changing with tech, state or law changes, added ship crew experience and reduced base literacy even further. Read the full patchnotes below for more information on all the changes.

As always, please report any bugs on [our bug reporting forums](https://forum.paradoxplaza.com/forum/forums/victoria-3-bug-reports.1114/)! We have also updated the [Known Issues post for 1.13](https://forum.paradoxplaza.com/forum/threads/known-issues-update-1-13.1919129/) with any fixed issues.

1.13.5’s checksum is `547c`, and you can check out the full patchnotes below.

The following changes have been made to the game compared to 1.13.4:

##### **Features**

- Added Ship Crew Experience. Ships will now gain experience while out on a mission, while participating in battles and when sinking ships. Experience will decay over time if a fleet is sitting idle in port. By accruing enough experience ships will increase their Veterancy Rank, which provides a positive modifier to accuracy, critical hit chance and readiness gain, with higher ranks providing larger advantages. The baseline accuracy bonus and critical hit chance for all ship types has been adjusted downward to compensate.

- The "Jeune Ecole" and "Capital Fleet" Navy Model Laws now also provide a starting experience bonus to ships

##### **Improvements**

- The supply ship allocation percentage is now a hard cap on how much ship construction is allowed to be allocated to supply ships

- Certain treaties now allow joining diplomatic plays again regardless of interest tier: alliance and support independence as well as guarantee independence and defensive pact when trying to join on the defense

- Added 'station in state' to right-click menu for military formations, also supports overseas stationing

##### **AI**

- The AI is now less gung-ho on supply ships and will not drive their economies to ruin endlessly building them

- Made a substantial pass on AI ship construction logic to make them more proactive about replacing obsolete ships gradually, instead of all at once

- Added better logic for AI navy composition, governed in the AI strategies database files

- Fixed a bug where the AI would select far too small fleets to transport their armies, resulting in the army being split into a myriad tiny stacks

- Fixed an issue where the AI was unable to ever pass Jeune Ecole

- Made the AI less willing to select event options that would increase Movement Activism if it is threatened by a revolution

- Made the AI more inclined to expel agitators with traits that increase Movement Activism

- Fixed a bug where the AI could get stuck on very low authority while unable to reduce authority spending

##### **Balance**

- Halved base literacy growth further, from 0.1% to 0.05%

- Abolishing the Edo Status System now requires Japan to abolish Subjecthood

- Public Schools now grant literacy growth per level of institution

- Philosophical Pragmatism, Central Planning and Analytical Philosophy technologies now grant literacy growth rate

- The Political Concessions amendment will now cost Authority proportional to its strength, and will not be available during negotiations if the country has insufficient Authority

- Bakufu is now required to enact Shinsengumi

- Made Iron-reinforced Hull consume some Iron instead of purely Hardwood

- Reduced the movement attraction impact caused by several pulse events - "The Flight of the Battleship \", "Antiquated Words", "Confusion and Delay", "Political Imprisonment", and "Cause Without a Rebel"

- Increased the Movement Activism effect of Political Concessions

- Ending Sakoku via the button in "The Locked Country" will now increase the Activism of the Sonnō Jōi movement equivalently to if the law was enacted normally

- Changed Itō H
