I guess that's some Battle of Bosphorus nonsense, honestly that DLC is full of bugs and ahistorical things. Basically all 3 countries - Greece, Bulgaria and Turkey like to declare ahistorical wars even with historical focus on. I turn off that DLC whenever I want a historical game.
Maybe disabling some focuses for the AI will do it. Thanks for idea.

I'm curious how this mod interacts with your mod. Seems like they are doing a lot of the same stuff. Maybe they should be combined honestly.

Yeah tahts a great mod. I went back and forth with historical immersion event pack, and soviet+ and better research mod. Them combined would be heaven on earth.

I've looked at the files in this Immersion mod, and there is no direct conflict. The only possible issue is AI, it seems this mod does the same 'tweaks' to AI to force it to do/not do something, if they combine, it might act weird at times. (Not declare war it should etc...)

And also my (few) events may happen as well as the new ones...

Maybe a compatibility patch?

Can you implement the fixes in this mod?

One of the things that bothers me with vanilla HOI4 is that basically all members of the Axis participate in offensive operations in a major way. For example the entire Axis invades Greece and the entire Axis invades the USSR. When playing as Greece I also find it very unfair and unfun. This is really unhistorical. Many nations in WW2 were not full belligerents. They were in a faction but they didn't engage in any offensive warfare. Bulgaria for example. Turkey as another example.

Basically only Germany, Italy, Romania, Hungary and Slovakia invaded the USSR. And the Romanian, Italian, Hungarian and Slovakian forces were small expeditionary forces not giant armies.

Only Germany and Italy invaded Greece.

Is there any way to model this?

Is Germany declaring war on Norway before beating Denmark intended?

Is Germany invading France before invading Norway/Netherlands/Belgium intended?

Shouldn't Spain have aircraft tech unlocked in 1939?

Is Japan making very rapid progress in China intended?

Is Cairo falling quickly in 1940 to Italy intended?

Is the Pre Arranged Territorial Expansion in the Balkans working? Doesn't seem to be in my game.

Also the USSR is sending large numbers of Volunteer Divisions to China including Tank Divisions. This has been a problem with the vanilla game since launch. It shouldn't be happening. The USSR's aid to China was limited to Nationalist China only and it was limited to material and Pilots.The aid stopped in April 1941 with the Soviet-Japan Neutrality Pact. Stalin never would have sent Divisions of troops to China.

Italy and Germany are still shipping huge numbers of troops to Ethiopia via the ocean.

Playing 1939 Turkey Balanced industry. Germany is doing very well in the USSR, they took Moscow, they are taking the Caucusus. Finland was destroyed pretty quickly by the USSR. Japan seems to be steamrolling China for some reason.

Playing as Germany Historical mode. The USSR isn't attacking Poland when I invade them, And after the invasion is complete the USSR is not getting any of the Polish territory.

What do you mean USSR isn't invading Poland? In the game USSR never fights Poland, the attack is modeled by the occupation of its eastern territories. It has always been like that. A war would make Allies fight USSR.
