May 7th Change Log

Crash

• Resolved a crash for late game enemy ship turns

• Resolved a crash when closing the Ship Designer

• Fixed a crash that could occur during game startup

• Fixed a crash that could occur during turn rollover or autosave while in or exiting the shipyard

Gameplay

• Fixed an issue where if a non-mining starbase was built near a resource first and a player tries to build a second mining starbase, the second starbase now correctly mines the resource

• Reworked the Sanctuary Lattice Module so pollution reduction now applies as a direct area-effect stat instead of a triggered modifier, which should apply more reliably, and the icon has also been updated

• Increased Ceasefire credit exchange from 200 to 500 when accepting and increased the penalty from 400 to 500 when paid to a rival, so ceasefire deals now carry more weight in negotiations

Ship Hull Rebalance

• Tiny Hull: Mass capacity increased from 6 → 7 (fixes AI building bombers with no weapons)

• Small Hull: Mass capacity increased from 18 → 20

• Medium Hull: Mass capacity increased from 36 → 40

• Large Hull: Mass capacity increased from 80 → 150

• Huge Hull: Mass capacity increased from 200 → 300

Improvements

• Industrial Center: Pollution per level now scales as a flat value instead of a multiplier (prevents runaway pollution on high-level worlds)

• Planetary Harvester (Synthetic): Pollution per level changed from multiplier to flat scaling

• Terran Grand Arts Center: Approval per level increased from 0.01 → 0.02

Hotkeys

• Resolved base game and console hotkey usage overlap

  • New console hotkeys are

    • CTRL + F1 - teleports the selected object to the cursor

    • CTRL + F2 - clones the object

    • CTRL + F3 - resets moves

    • CTRL + F4 - deletes the object

Localization

• Added in translations in all supported languages for the new planet and resource context windows and adaptive AI settings

Map Generation

• Rebalanced map setup values across all density presets

Text

• Removed duplicate text for Drengin messages
