Update: Dec 11 @ 3:03pm

Germany on the eastern front:
- forbid German AI from launching invasions early (that get cutoff, or raided by subs or both)
- German AI will build more fighters, which hopefully counteracts the extra allied fighters in Russia
- AI will pause its attacks sooner if it’s clearly not working and it’s just ‘grinding metal’

- improved how German AI creates tank templates (should remove light tanks earlier)
- various tweaks to german AI production and tank templates (added light and medium SPGs to some of them)
- AI will produce more submarines
- Japan AI will do some historical focuses at more appropriate dates
- major AIs will pick appropriate Air Grand doctrines in historical mode

Update: Dec 4 @ 4:03pm

Mod updated for 1.17.2.0

Update: Dec 3 @ 11:29am

Mod updated for 1.17
- fixed an issue that made US AI produce only basic heavy fighters and not create better templates
*Changed the mod name

Update: Oct 19 @ 5:31am

1.16.10
- reduced the obscene amount of mothership aircraft AI tries to produce, often crashing its economy from lack of material and all CIVs being used for imports. This also stops the AI from replacing all the other aircraft types with motherships.

Update: Jun 22 @ 3:46pm

Mod updated for 1.16.9
- UK AI will try to improve relations with USA to make them more likely to help via their decisions
- removed an old 'cheat' AI event that is no longer necessary, this will give error warning in the saves, but should not cause any problems

Update: Jun 15 @ 7:50am

1.16.8
- only very minor changes

Update: May 20 @ 5:12am

Update 1.16.6
- fixed some errors in non-NSB AI modifiers which would prevent AI from researching certain techs (mostly TDs, SPGs)

Update: May 2 @ 1:00pm

Mod Updated for 1.16.5
- added historical airplane presets for France and fixed the default icons/3D models

- some more fixes to German tank icons and modules
- made flame tank presets (if they exist) visible in the designer and made them use correct tank chassis
- German AI will no longer create artificial Reichskommissariats out of friendly countries that are already their own puppet or in a faction with them
- German AI will no longer create Norwegian RK, as it is simply incapable of handling the resistance there (not enough manpower)
- German AI will produce a bit more heavy fighters
- UK and France will stop re-guaranteeing Czechoslovakia and Lithuania after Munich conference
- chinese/japanese warlords will hire army advisor much sooner – this fixes AI not recruiting new units, because they don't have any 'valid' infantry template (and no XP to create one)
- fixed Raj not hiring any army/navy advisors
- China and chinese/japanese minors will use correct division namelists for infantry/garrisons
- improved what advisors the chinese warlords and PRC pick

- Guangxi Clique will also build few dockyards to produce convoys / later ships if not conquered
- Siam will keep some reserve troops in Siam instead of spreading its army everywhere around China and pacific
- many other minor AI adjustments

Changed some AI ship ratios
- UK will not try to build so many battleships and carriers and lack screens as a result
- Italy will also build other ships than battleships, especially if it loses too many screens

Update: Apr 9 @ 12:25pm

- Japan AI will now use bicycle divisions and occasionally build a mechanized division
- German Reichskommisars will stop trying to raise divisions and waste manpower
- Germany will stop sending tank divisons to Norway instead of focusing them in Benelux
- Soviet AI will try to protect Moscow more

Axis Armor pack DLC
