Is it possible to make it compatible with RT56 mod?
KubiG  [author] 16 Jul @ 1:52pm 
Yes it is, AI considers it superior to any fighter, wheter that's true or not. Unfortunately I haven't found a way to reduce or at least regulate their production... Since it's a GoT feature handled separately from normal aircraft designs where I can setup what is 'good' and what is not. Once the AI researches motherships (which is very random), they'll switch to them.
Space Marine 16 Jul @ 6:34am 
Is it normal for the AI to be obsessed with Mothership Aircrafts? They put most of their factories into producing those instead of regular aircraft such as Fighters. I don't know if Mothership Aircrafts are THAT good, but i don't think they can beat regular Fighters in Air Superiority

It shouldn't conflict, but why don't you try it yourself? If the deposits do appear, there is no issue.
Riekopo 1 Jun @ 10:47am 
Conflict with the Middle Eastern Oil mod?
KubiG  [author] 1 Jun @ 4:23am 
Light tanks? Like after ww2? That shouldn't be possible, I've made the AI actually stop light tank production altogether once they get to T-34. I hope it's not some negative value overflow xD
Space Marine 31 May @ 3:16pm 
Comment below made a good point. Saw that happening on a game of mine as well, the Soviets had like 300 factories on light tanks
啊这 31 May @ 3:15pm 
A bug where Sov would produce a lot of light tanks in the later years instead of medium or modern tanks.
KubiG  [author] 5 May @ 10:44am 
I don't think so, the tech tree might be messed up.

compatible with R56?
Space Marine 2 May @ 1:16pm 
Oh okay, thanks for the response. On my past couple of games, the German AI did everything right, so i guess it was just a rare moment i witnessed
KubiG  [author] 2 May @ 1:08pm 
That happens if Germany doesn't train enough units in time (some focuses require certain army size). I've seen it, but it's very rare. It also doesn't really affect the war (it doesn't delay future war declarations), Phoney war is just a little shorter.
Space Marine 25 Apr @ 5:24pm 
Bug report? The German AI in my games is taking a while to declare war on Poland and are usually doing it around November to December 1939. Is this happening to someone else?
Counter Culture 9 Apr @ 3:02pm 
goated update, this mod is always a better time to play with than vanilla. Thanks for taking the time to keep it updated!
Ackbaraddin 19 Mar @ 7:02pm 
I fixed problem. Before launch the game I gave x2 buff for Soviet Union and I have another question. I can't see germans in Libya and I don't know why but Italy only holding Ethiopia. Can't you fix this? Btw I am appreciated because you fixed operation torch. Thanks a lot...
KubiG  [author] 18 Mar @ 10:28am 
Or just load an earlier save and try again. Sometimes the German AI gets lucky and encircles a lot of Soviet Divisions and pushes very far. It's really random, other times they can get stuck just a few states away from the initial border and people then complain that Germany is too weak. xD
Ackbaraddin 14 Mar @ 4:02pm 
I sent almost all my equipments but it didn't make any difference :(
KubiG  [author] 14 Mar @ 3:51pm 
You need to send them as much LL as possible. German AI is much better since GoT came out.
Ackbaraddin 14 Mar @ 8:27am 
When I play US or UK, soviets dying on 1942 I dont know why :(
KubiG  [author] 6 Mar @ 9:15am 
It's almost done, maybe tomorrow.
Riekopo 6 Mar @ 6:23am 
Will it be a while before this mod is updated for the new DLC?
Riekopo 23 Jan @ 8:06pm 
I see, Devs should implement that in vanilla. Is there any way to modify Turkey on Historical so they join the Allies but do not participate in an offensive fashion outside of their home territory? There are many counties that joined one of the factions but did not fully participate. HOI4 has a major problem with every country joining a faction and then acting like they are a world superpower and sending their armies all over the world.
KubiG  [author] 23 Dec, 2024 @ 9:02am 
In vanilla they just join the Allies in 1943 no matter what. This is ahistorical, they joined 1945 and only after Germany was basically already collapsing. They did not fight in ww2 in any relevant capacity.

In the mod there are certain conditions that the AI checks, basically:
1) If Allies are winning and it's 12/1944+ it goes the Allies path
2) If Axis is winning and it's 5/1945+ it goes the Axis path
3) If neither is winning they won't do any further focuses and remain neutral (unless attacked ofc)

It requires historical focus on.
Riekopo 18 Dec, 2024 @ 6:42pm 
Can you explain the changes you made to Turkey with regard to which faction they join? I'm not seeing any difference in my current Germany 1939 game.
modelcitizen 16 Dec, 2024 @ 4:08am 
Many thanks for your continued support.
donald.grape 7 Dec, 2024 @ 8:30pm 
Oh... maybe it was another mod doing this. After all, I do use a lot of them.
KubiG  [author] 7 Dec, 2024 @ 8:25pm 
#donald.grape I have never observed such issue and I've done dozens of AI-only runs with my mod. No idea. Also this mod doesn't make any substantial changes pre-1939 beside making Germany attack 3 months later and having slightly different templates and more tanks.

#Riekopo - that has always been the case with 1939 scenario. I think it's because all countries start with some equipment deficit, and generally a bit smaller armies. So they don't have anything 'to spare'. That's why I buffed China a lot. It still loses from time to time though.
Riekopo 6 Dec, 2024 @ 6:20pm 
China doesn't seem to be getting any Lend Lease support from anyone and seems to be performing kinda bad against Japan. This is with the 1939 start and Balanced industry setting.
donald.grape 6 Dec, 2024 @ 1:37pm 
WIth your mod, Germany has real trouble getting past BeNeLux. It's not unusual for Italy to take France before the Germans do.
Moni_8_8_ka 30 Nov, 2024 @ 11:51am 
Thank you for updating the mod i will play it and test it as soon as i can and might give you feedback.
KubiG  [author] 29 Nov, 2024 @ 8:30pm 
It builds them and then uses them for raids. Not sure if they can actually paradrop somewhere though.
donald.grape 29 Nov, 2024 @ 5:55pm 
Wait? The AI now can use paratroopers?
KubiG  [author] 20 Nov, 2024 @ 2:47pm 
AI is much better, the Force Concentration really helps Germany, they can kill Poland faster than me and Barbarossa isn't a WW1 simulator anymore. :)) But it seems to be having some difficulties with the MEFO bills and running out of PP, that's what I'll try to improve. They often end up stuck in Extensive conscription and no manpower.
Space Marine 19 Nov, 2024 @ 4:16pm 
Nice, good to know. Germany has become quite differently and i'm still getting used to it myself, especially now with the research stuff. Still have no idea how the AI is performing as Germany as i bring a few mods to get a better Historical game
KubiG  [author] 19 Nov, 2024 @ 2:33pm 
No not yet.
Also it will take me longer than usual to update this and get everything working again, because so many of the things changed with the latest patch.
(And I have to first re-learn Germany myself lol)
Space Marine 19 Nov, 2024 @ 1:53pm 
I'm guessing this isn't working with the latest update? Since Paradox made some changes to the AI.
Riekopo 15 Nov, 2024 @ 6:14pm 
new DLC/update released
KubiG  [author] 20 Oct, 2024 @ 3:26pm 
Yes ofc it does.
Crispin 12 Sep, 2024 @ 12:57pm 
Thank you.
KubiG  [author] 9 Sep, 2024 @ 2:25pm 
I've uploaded a new mod version, -per update notes- if you encounter CTDs while using this mod, I recommend starting a new game (not loading a save), that fixes the issue. The latest war effort patch made changes to a game file this mod needs and it made the game unstable. Unfortunately saved games keep the original and it causes problems...
KubiG  [author] 25 Aug, 2024 @ 9:55am 
The Allies are a bigger threat, and USSR certainly is a bit more durable, but I'm afraid as Germany if you know what you're doing, unless you buff the enemy AIs considerably, and/or deliberately avoid any meta designs and AI exploits/weaknesses, they'll have a very hard time 'defeating' you. Mods can improve the AI only to a limited degree.
Space Marine 24 Aug, 2024 @ 3:40pm 
Does this make the Allied better in dealing with the Axis in Europe and Africa? I'm looking for any mod that can make the Allies win in their respective theaters and not be stuck sending countless divisions to die in naval invasions in Northern Italy, Greece or Romania in 1942. I'm basically looking for a way of losing as Germany historically
KubiG  [author] 22 Aug, 2024 @ 7:34am 
Japan seems fine. Yes Germany struggled quite a bit for some time, the latest 2 mod updates were aimed at fixing that. It seems I found a solution that works for the AI and I'm happy with it.

I never really found out why was it happening. My theory:
Part 1: The Phoney War makes it more difficult for Germany to prepare (less time, less equipment)
Part 2: The Allies fight back more and had a tendency to wipe out Luftwaffe (which is kinda historical), but if they lost too many planes they couldn't defeat USSR's airforce quickly enough, Part 3: Germany's templates weren't very good
Part 4: Soviets play better in this mod and are harder to defeat (at least I think, some people commented they are harder to kill)
donald.grape 21 Aug, 2024 @ 1:52pm 
Correction: Sorry for the mistake, Japan does indeed get Ichi Go. So how about make Germany stronger in the east? They can barely reach Minsk and Kiev, that's worse than without the mod where they reach Leningrad and Moscow.
donald.grape 21 Aug, 2024 @ 1:08pm 
Could you make Japan pick Ichi Go decision to have an easier time in China?
modelcitizen 30 Jul, 2024 @ 8:21pm 
Thanks for another update. As usual, great work!
TERRAKOue 7 Jun, 2024 @ 4:48am 
Improved AI Research compatible with Reworked Air Designer?
Counter Culture 29 Mar, 2024 @ 10:17am 
Thank you for your continued work on this mod, always a better experience when using it!
donald.grape 5 Feb, 2024 @ 4:33pm 
Could you make so that China annexes XSM and Sinkiang when it is a puppet of Japan? If you played this, you should know exactly what I'm talking about.
Crispin 5 Feb, 2024 @ 2:01am 
Another great update cheers.
