What changed
- Gameplay
"Red Ball Express" (1.1 patch) is now ready, check out the patch notes if you want to see details on what has changed.
AI - Tweaked deployment AI to not get crippled when their armies are taking damage. - Air mission AI is better at prioritizing the most important regions in stead of getting stuck in local optima of groups of regions. - Tweaked down AI desire for motorized a bit. - Added scriptable AI strategy to tweak factory assignment to equipment types and SIGNIFICANTLY boosted fighter production. - Tweaked up AI production balance for infantry equipment. - Tweaked guarantee desire to go down the more enemies a country has. Should keep Allies from going guarantee crazy while in wars. - Added a define for min steps for unit controller to strategically redeploy to front location and boosted it from 4 to 8 to reduce lots of small redeployments along fronts. - Made AI capable of determining if a template was created by them or not. Germany should no longer replace their divisions with templates from Austria. - Tweaked area defense and pocket handling AI to be better at handling coastal defense. - Tied countries naval base IC fraction to their naval AI focus, primarily meaning Germany will not be building as many of them, at least initially. - Improved unitcontrollers capability to recognize when units should join as support in a combat (effects both player and AI). - The AI now launches naval invasions against the same enemy area at the same time rather than separately. - Tweaked AI template designing - Having a common enemy will now make AI very accepting to granting and accepting military access as long as both are democracies. - Neutral countries now consider guarantees when deciding on which faction it would rather join. - AI is now properly checking if having common enemy when looking at asking for and granting military access, and is also more eager to do - Soviet and Germany should no longer bail from the Unholy alliance as soon as they can - AI containment score no longer goes massively negative if a major is farther away than germany meaning Allies can guarantee vs soviet aggression if they are worse than Germany - Made non-core states count as half compared to core states when deciding on number of units for area defense. - Added Women in Aviation to historical focus list for soviet - Moved Claims in Baltic up the historical focus list for soviet - Improved AI naval deployment to strategic regions - Tweaked front assignment AI. Should mean AI is better at multi front wars. - Further tweaks to AI front assignment to attempt to reduce bad stuff happening in multi front wars. - Further tweaked the AI front balancing, and made sure France does not completely mess up their Italian front and Germany pushes hard against Poland when war breaks out - AI should now be able to respond to naval invasions with naval bombers - Made sure fascist majors are much more likely to go for war economy - Polish AI will no longer randomly change its ideology by picking ministers - AI should no longer use garrison divisions as infantry. - Changed trigger condition for UK focus Benelux Intervention to require a bit more fascist/communist support, preventing the AI from taking it immediately. - Naval AI will now deploy all its fleets (previously it would generally deploy less than 1/3 of all its ships). AI will now split fleets it cannot find a mission for, allowing it to spread them
