• We have updated our Community Code of Conduct. Please read through the new rules for the forum that are an integral part of Paradox Interactive’s User Agreement.
Besides what Tom013 said (which is always a good idea when you have a problem in any Paradox game), you might want to also try clearing out your GFX folder under Documents. There's an option in the launcher to clear out everything under Documents/Paradox Interactive/Hearts of Iron 4 with the exception of your save games. I've seen that black flag issue before in other Paradox games, and that's usually the fix from what I remember.
I assume you mean the user directory? only thing the launcher provides, if so it did work to some extent but not by much, thanks for the suggestion though!

Yes, that would be it. If clearing out the user directory didn't do the trick and assuming you're not using any mods, probably all you can is do a clean reinstall at that point. Move the entire user directory elsewhere, and after uninstalling the game make sure there's nothing left in the installation directory.

Beyond that, you're probably going to have to have a word with the Tech Support forum as Tom013 says. If you need to do that, you'll have to sync your Steam account in order to gain access. That also has the added benefit of unlocking the other hidden forums such as the modding forum.
 
I was thinking some SPG might give my divisions staying power and some soft attack too.

SPGs reduce your divisions staying power since they have no org. It does greatly increase their soft attack though, and is great if you want better performance against soft enemies, which tends to be 90%+ of what you face.
 
Armored units can be optimized for offense or defense, and against particular specific opponents. The strengths of the armored arm are offensive. Offensive action is usually against infantry divisions, where ample soft attack to overwhelm their defense and armor enough to avoid being pierced by them will weight the fight in favor of the armor. The objective is to overrun enemy if possible, but generally to cut through and turn salients into fatal pockets that can then be ringed with infantry and crushed.

SPGs help with soft attack and improving average armor. The motorized troops (or cavalry or infantry as the fallback expedient) are critical for defense and org stats because these are not likely to be high for offensive armor divisions, and a characteristic of offensive armor divisions may be an inherent vulnerability to sustained enemy attacks if thrown on the tactical defensive. Armor, as a rule, should fight and then be pulled away from the battle line to reorg and replenish equipment for the next offensive impulse (of course divisions intended to rip up enemy armored attacks are built and operate differently.

A division with 30% tanks, 30% SPGs or motorized rockets, 30% motor infantry (or substitute) and 10% extras such as other armor variants is general purpose - 0 width to have real punch, though if fielded early likely to be a template built up step by step. Medium SPGs have better soft attack and armor, which may be necessary to counter enemy equipment improvements as the war goes on.

Another rule of thumb is armored divisions should operate together in groups of 2 or more, and have at least double and more their number of infantry divisions to hold important ground and do the bulk of the fighting and all of the heavy work in sealing and reducing pockets.
 
I dont understand.. in hoi4 wiki those "- "and "+ " combath width..
example : mass charge +50% combat witdh .. so max 80width can be now 120? or my 40 width division use 60width in battle?
heeeeeeeelp

Clean install did not work :( How does one sync up their steam account?
 
It seems to happen quite a bit, though there are other times when it doesn't and you get Yugoslavia through the NFs as well. Yes, it does shut down continuing down that path, but you do get a free justification against Yugoslavia.
 
Gonna be honest, i am completely new to this forum mlarkey, how does 1 find the subforum? I got onto this page on a total whim tbh :p
You mean the tech support forum? It's right off the main HoI4 forum, pinned towards the top of the page along with the modding, bug report, and MP forums (all of the individual game forums are set up the same way). If you still need a link though, here: https://forum.paradoxplaza.com/forum/index.php?forums/hearts-of-iron-4-tech-support.952/
 
How much lend lease infantry equipment, supplies, trucks, and Artillery do you send to China, and or the Allies?

I have been playing the 1939 start date as USA. (No stockpiles of old equipment to share)

I want to know how to stop Japan from winning in China.
 
China was buffed recently to be a tougher fight for Japan.

The first thing China needs is convoys, which are needed to collect LL. China starts able to use rifle kit, Great War Tanks, fighters, and tactical bombers. You can expect it to research artillery to be able to use it. It is typically short of everything - particularly infantry kit.
 
What causes damage to land forts?

I guess fighting in the province has a chance to damage a fort. But I noticed that, playing France and Czechoslovakia against the AI, each time the war starts, up to 5 levels of forts in one province are damaged almost immediately. Someone mentioned that strategic bombers could damage forts. Is this correct? I tried a test run with Germany, sending several hundred strategic and tactical bombers against the maginot line, with no success. Are there any other things to consider?

Yes, strategic bombing runs will damage land forts. The key here, is that you cannot repair anything in a province that is under attack, so if German AI maintains regular attacks on the Maginot while also strat bombing, eventually they'll knock them down. Even the repair national focus won't help, since they're under attack.

What's likely the culprit of your poor success in strat bombing is a combination of not attacking- and therefore not preventing repair- as well as poor RNG. Currently there is no way to target individual areas of an airzone, choose particular targets, or even to narrow down the list of potential targets for strat bombing. You may just be getting unlucky and your strat bombers damage infrastructure in Paris, or hit a civilian factory in Normandy. There isn't really good feedback on the results of your bombing runs other than "yep, stuff is indeed being bombed" I don't have information to back this up, but it seems the AI has some way of focusing fire on particular targets it wants to hit. I remember failing a Democratic Denmark challenge because my line of level 7 forts got bombed to the stone age, while my military factories and infrastructure never seemed to get hit.

IIRC, the only other way for improvements to be damaged is through partisan activity... which I'm fairly sure the French don't have to worry about in their core territory. ;)

The big takeaway is that in order to maintain a wall of forts, you're going to want air control. Either standard fighters with upgraded weaponry or heavy fighters can knock back strat bombers, and static AAA in your states make a big difference as well. This may be just a theory, but I think static AAA reduce the odds of that particular state receiving strat damage? Might be a coincidence, but I found in a France game my fort lines didn't seem to get bombed with level 5 AAA in Alsace. That's just a guess.

Hope that helps!

mmmh. When I've played A-H, I'm pretty sure that the CZE border fortifications get damaged as GER assaults them. They certainly haven't been strat bombing.

Oh yes, fighting in a province still deals some damage, don't get me wrong. I didn't mean to imply that it didn't. Often times though, the effect of bombing can dwarf the small amount of damage caused by the fighting. Air control is still very powerful in avoiding fort damage.

In a case of Germany vs Czechoslovakia, there just generally aren't enough defenders manning the forts to knock down the attacker's organization quickly enough. The longer the battle takes, the more province damage, and the more casualties inflicted on defending troops.
