Custom Population, Province Defense, and Dynamic Army Size Limits

This June 4, 2026 update focuses on custom province population, province defense, and dynamic army size limits.

Custom population and defense:

• Added custom population settings to the Province panel. You can now set current population and max population for a province.

• Max population can be locked so load validation and map recalculation will not overwrite your custom value unless it is invalid.

• Added custom defense settings to the Province panel. You can now set current city defense, max city defense, and home battle efficiency.

• Custom defense values also support locking, giving custom maps and scenarios more stable province-level control.

• Added district population settings. A total district population can now be distributed across all provinces inside that district.

• Army size limits now scale dynamically with province population, so more populated provinces can support larger armies.

Custom map images:

• Added support for placing custom images directly on the map.

• Images can be dragged, scaled, rotated, replaced, copied, hidden or shown, and adjusted with transparency controls.

• Custom map images now support layer selection and order within the same layer.

• Image data is saved with the map save file.

District editing:

• Added a Set as District Center action and a dedicated city icon for district centers.

• Districts can now share the same name, and district color storage is more stable.

• Improved district editing performance, especially painting, erasing, color refresh, and button state refresh.

Optimization:

• Optimized runtime caching for custom military unit setups, reducing repeated calculations during battle and UI queries.

• Autosave can now run normally while the game is paused.

Bug fixes:

• Save files are now identified by absolute paths instead of temporary indexes, fixing cases where same-name saves, Workshop saves, or changed sorting could select the wrong file.

• Save names now filter invalid characters, and saving uses a safer atomic write and backup flow to reduce the risk of corrupted saves after interrupted writes.

• Fixed Workshop map uploads sometimes using the wrong save path, reusing an old upload folder, or leaving old .save files behind.

• Fixed abnormal ordinal naming order when countries are restored or rebuilt.

• Fixed unstable selection state, color assignment, and refresh flow while painting districts.

• Fixed old province overlay display sometimes remaining in height view.

• Fixed custom label scaling being affected by map zoom.

• Fixed district name labels drifting after setting a district center.

• Fixed attack arrows sometimes being forced to full visibility during their fade-in animation.

Follow-up plan:

The new major national economy update needs to be delayed for a while. Its current values and in-game behavior are still not polished enough. I hope to release it by the end of the month. Thank you for your understanding.
