Smart AI Construction

[Compatible with 1.13.9] / (Military Deletion Bug Hotfix)

This mod is a conservative AI asset management mod designed to prevent AI countries from going bankrupt due to reckless management.

The 00_default_strategy and AI define files in this mod overwrite the vanilla files (NON-REPLACE). Therefore, it may not be compatible with some other mods.

1.13.9 Changelog

In the 1.13.9 update, the issue where AI countries went bankrupt by over-expanding barracks has been resolved, so the military size configuration file has been removed (AI will now maintain military strength at the vanilla level).

Increased the AI’s weights to invest more in shortage goods, construction materials, and military supplies.

While the randomness of AI building investment has been increased, the weights for highly profitable industries have been raised to encourage diversified investment. Other investment-related fixes.

※ Fixed a bug where the entire military was deleted due to a missing code snippet. I will inspect the code more thoroughly next time. 😓

The Purpose of This Mod

Since the 1.13 update, vanilla AI countries have suffered from skyrocketing expenses, making it practically impossible for them to manage their economies stably into the 20th century. To resolve this issue, I have conducted continuous testing since previous versions and have been uploading solutions one by one to my mod collection.

This mod is specifically designed to address the flaws of version 1.13 while ensuring stable competition. It enforces highly stable and conservative fiscal policies so that AI nations—especially Major and Great Powers—can avoid falling into bankruptcy cascades.

Compatibility & Testing Environment

This mod has been thoroughly tested and verified using only the following mods (with no other mods active):

Building Preference Rebalance (BPR)

Shipping+Shipyard buffs mod

Note: The 00_default_strategy and AI define files in this mod are non-replace files (they overwrite vanilla files completely). Therefore, it may be incompatible with certain mods that alter the same files.

1. Construction Sector Expansion Mechanism Changes

Population-based scaling downscaled: The divisor for the AI’s construction sector investment relative to population has been increased by nearly 1.5x, reducing the tendency to over-expand construction sectors simply because of a high population.

Weekly income-based scaling downscaled: The divisor for construction sector investment relative to weekly government income has been increased by nearly 2x, reducing the phenomenon of over-expanding construction sectors just because the country has a high weekly income. Note: This is to fix the vanilla Victoria 3 issue where the AI spams construction sectors based on gross revenue without properly considering the weekly net balance. As a result, the AI will now invest much more cautiously.

Blob & GP bloat removed: Removed or significantly reduced the extra scaling values applied to populous nations, Great Powers, Major Powers, journal entries, and national strategies, cutting down on unnecessary construction sector bloat.

Investment pool scaling buffed: Conversely, the divisor for construction sector investment relative to the investment pool income has been halved. This allows countries with fast-growing investment pools to invest in more construction sectors, ensuring capitalists can stably roll the snowball even when government construction is paused.

2. AI Define Tweaks
The AI will avoid expanding its construction sectors when the economy is in a critical state.

If gold reserves drop into a negative state (debt), the AI will pause constructions much faster and look to raise taxes. Construction will only resume once the debt is mostly cleared.

The AI will invest much more aggressively in raw materials, construction materials, and military supplies.

Various other minor tweaks.

3. Miscellaneous

The minimum enactment chance required for the AI to start passing a law has been reduced from 50% to 20%, encouraging the AI to reform laws much faster.

[Highly Recommended to Use Together]
This mod is highly recommended to be used alongside the main mod. It dramatically increases the AI’s weight and priority for constructing raw materials, resource factories, steel mills, and paper mills, while simultaneously lowering its preference for plantations and redundant railways. This strategic adjustment guides the AI to optimize its construction queue with maximum economic efficiency.
