NCNS: Patch 1.17.2

Commanders,

Our Allied Headquarters has implemented a suite of changes we previously outlined in the recent Studio Gold Updates and as a follow-up to NCNS Patch 1.17.1.1. The work spans balance adjustments, gameplay improvements, stability and bug fixes, and a variety of interface and AI refinements.

We continue to read your bug reports after the No Compromise, No Surrender release and greatly appreciate the steady stream of feedback. If you want to help improve the game, please consult our guidelines for writing a bug report.

Balance

• Introduced two state-building options that scale with infrastructure level: one reduces energy consumption, the other increases local resource yield efficiency. These two buildings are mutually exclusive within a state.
• Setting energy demand to zero no longer imposes a production penalty.
• Infrastructure-origin resource yield reduced from 20% to 15% (note: the new building can still result in higher overall yields in some cases).
• Commercial Nuclear Reactors now reduce state energy consumption by 50%, up from 25%.
• The Electronics Concern now reduces factory energy consumption by 10%.
• The Industrial Concern now grants 6 Coal and increases coal gain efficiency by 5%.
• Replaced Equipment Conversion technologies with Energy Gain Efficiency technologies; each grants +15% energy gain per coal.
• The first four Machine Tools technologies now additionally grant +20% equipment conversion speed.
• Factories gained through resource exports now contribute less to per-factory energy consumption.
• Added a cap to per-factory energy consumption.
• Refined AI research priorities for Excavation and repurposed associated techs to account for coal.
• Excavation technologies now provide an extra +5% coal gain efficiency.
• Chinese warlords retain a starting trait when they become leaders under alternate ideologies.
• The shared Chinese focus “Invite Soviet Advisors” now grants a national spirit that boosts army experience and organization; several NCNS shared branch focus durations were also aligned with the non-NCNS versions.
• Reduced destroyer surface visibility bonuses in the “Patrol Boats” and “Light Task Forces” subdoctrines to -5% to prevent excessive stacking.
• Added a number of light tanks to the Nationalist China reserve to better reflect historical prewar inventories.
• Lowered influence gains from shared scientists in factions.
• Made political power gains from warlord subjects both smaller and visible.
• Stopped Nationalist China from needlessly sending support to Hebei–Chahar.
