Paradox has shipped Victoria 3 hotfix 1.15.1, live today with checksum f843. It is the first round of bugfixes, balancing and improvements since Update 1.15 and the State and Revolution immersion pack launched on November 5.
Improvements
Regime Change now lets the target country adopt laws it normally could not, such as Council Republic, as long as the country imposing the change already has those laws enacted. A Regime Change also establishes friendly relations with the target: interest groups put into power join a lobby favouring the imposing country, while groups forced out join a lobby opposing it. The Appoint Favorite character interaction can now be taken once every six months, and Revoking Favoritism once every five years. A White victory in the Whites and Reds journal entry now guarantees Russia cannot decrease Congress Poland's autonomy or use the Install Favored Ruler overlord action for ten years.
AI
The AI now counts the wages of new jobs as a cost when picking production methods, and counts only workers actually laid off as wage savings. It properly weighs goods output and input multipliers, and a bug that made it avoid production methods needing more skilled workers has been fixed, which especially held back its use of electrical production methods. Its mobilization target is now capped by the 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. The AI also prioritizes advanced industrial goods such as radios, telephones and oil when it makes sense, scores labor-saving methods higher where workers are scarce, no longer subsidizes profitable buildings or ones it does not genuinely need, and budgets mobilization spending to the severity of the war. British and Russian AI weights in Persia have been corrected, and the AI now uses the anchorage production method for ports when it has no need of Merchant Marine.
Balance
Copper has had a pass over availability: it is now more available and less consumed by industries. Paradox says it is still monitoring feedback on the resource. 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, and the starting technology for Waterboersland and Philippolis has been updated.
Bug Fixes
Personal Unions can no longer appoint favorites, Acquire Land in Panama now hands over enough land to build the Panama Canal, and a fleet trying to merge with an unreachable fleet no longer gets stuck trying forever. Exiled armies can now move to a port to be transported, prestige can no longer drop below zero, and Regime Change is no longer available against countries where no law change would take place. A revolutionary movement no longer turns into a secession by default when another movement overtakes its revolution, Ukase modifiers are now properly removed when the Emperor and Autocrat journal entry fails, and the Synod of Polotsk event now applies its Crypto-Uniate Communities modifier. Interest groups no longer vanish from the Government panel after changing laws to Autocracy until a week passes, paused construction sectors are no longer counted in some private investment decisions, and Congress Poland can no longer side with Polish secessions through regular diplomatic play while the Whites are dominant.
The hotfix also touches art, audio and interface: the Russian building set now appears in the Ural, East Karelia and Kola Peninsula regions, the new Prestige Goods icons are hooked in, Rosa Luxemburg wears period-appropriate clothes and a hat, the State and Revolution main menu theme plays for owners of the immersion pack, and the market panel gains a World Market Hub filter. Performance when selecting multiple armies is improved, and modders get a new can_secede_during_revolution flag.
