HOI4 Dev Diary - We're back! (and 1.4.2 patch)

Hi everyone! The HOI team is now back after recharging batteries on summer vacation (although yet again I failed to go visit the submarine museum in Kiel :().
We decided to start our time off with a little patch (Oak 1.4.2) since there were still a bunch of things we wanted to deal with for which there was no time before summer.

Here is changelog:
Code: 
######################################
###########  Hotfix 1.4.2 "Oak" ###########
#####################################

##################################
# AI
##################################
- Added AI strategy to avoid some naval strategic regions
- AI now realises that puppets will also join the war when their overlord does ( fixes situation where China does not put any troops on their border with Japan's puppets )
- AI should now prefer even shorter naval routes when picking what ports to navally transfer between
- Nations with low manpower are now less likely to burn pp on relation boosting as they need it for laws
- AI should be less likely to waste PP on guarantees when low on manpower and at war
- Removed AI weight modifier is_in_faction from JAP axis leaning focus
- Tweaked ai weights for carrier plane research. AI will now always research the most modern carrier version available and not research any carrier planes if they don't have carriers, the US and Japan will also be more eager to research carrier planes and particularly so when at war with each other
- Tweaked AT gun research to take enemy armor values into account (AI will be more willing to research AT upgrades if facing an enemy with high armor divisions)
- AI will no longer research basic heavy tanks if it can already research improved heavy tanks
- AI now clears the trades that are not being fulfilled due to having no access to trade country
- Italy should now be more careful about transports across the Med
- Enemies of UK will now be wary of transporting through the english channel

- Fixed a horrific bordergore issue in Romanian "Split CZE" focus
- Ensured that split CZE event chain did not result in CZE units sitting around after their country got annexed
- Doing the Indian focus "Battaglione Azad Hindoustan" should now fire the proper event for Italy rather than give them the option to collect money for the RAF
- Cheating on the Austria-Hungary Referendum and going with the annexation should no longer report that Hitler was assassinated. (the proper news event should fire instead)
- France now joins the Czech entente if they decide to support the Czechs and Czechs have their own faction

##################################
# Stability
##################################
- Fixed a division by zero CTD in airmissions when aircraft are fighting missiles
- Fixed various rare CTDs

As usual for patches between DLC releases we put them in public beta first. I snuck this one up yesterday and it was updated with some extra fixes today. If you want to test it out in beta you can find out how here. If all looks ok we may update live tomorrow evening (earliest), or on monday.

Looking over changelog list you'll notice how we have again added more portraits for free. This is part of our ongoing project to make sure all starting nations have unique portraits and its not that much left now either. I expect us to have accomplished it by 1.5 hopefully! Here are the portraits that were added:

We have also been working at an old and very difficult AI problem. The classic where Italy ships troops to Germany to help out (often from africa) leading to slaughter as they go through the channel. Our solution for 1.4.2 is specifically to deal with issues in the channel and the Mediterranean and works by us highlighting particularly dangerous areas to AI. Whenever AI needs to transport through such an area to reach another front and danger is high enough it will instead use those troops somewhere else. So for example Italy would leave troops in africa and fight on those fronts rather than get them killed moving to more high priority fronts. Long term we want to come up with a dynamic solution for this that doesnt need us pointing our danger to the AI and ways it can adapt its strategies based on this. AI however is always a work in progress for improvements and I think we have made a good step forward for a more competent transportation AI.

For today's World War Wednesday stream we are going to try something different: A massive co-op game where each general in germany is a different player on the dev team and me and Daniel run the government. Its going to get interesting so tune in at 16:00CEST on https://www.twitch.tv/paradoxinteractive!

See you next week for another diary!

I hope you will make gfx for american and russian equipement too
 
God. I envy those sweedish Vacation time that was almost two mouths. Now Turn up the war machine and please, fix germany on single player, if you use Historical focuses, and pick like butan and just watch, the AI will totally die in like 1940... Axis is a way too weak in Single Player... So if you want a fun game between the three factions, you need to play as some Axis Majors otherwise the axis is not a threat at all.
Also, hello guys, I'm new over here. I've 600+ hours in HOIV, but I've never been into Foruns that much.

I don't see this at all. They are oftentimes reckless regarding aggressiveness and get into multiple-front wars which they can't win but they are not weak.

Thats exacly what I meant. Sorry if I wasn't clear, but thats it, they don't secure a front before creating another, they don't protect ports, they transport their resources through dangerous waters those things make them die really soon. No player for or against them, AI Axis vs AI Allies, Allies do really better always.

I don't know how it plays out in historical SP because never tried that. In non-historical SP much depends on the focus choices (which are randomized). E.g. if Axis gets into an all-out war against France, Britain, and the USSR at the same time it's almost certainly over for them. If they get the USSR defeated before attacking the West it will almost surely be a victory. My last semi-handsoff game (i was CZE but overrun by Germany and left on handsoff) ended with almost total Axis victory, only the USA was spared but there they have overrun the USSR before going against the Allies.
 
I have no idea how this is possible, @podcat, but ever since the beta-patch I have been unable to start the game. Other games start in Steam just fine, but HOI IV does not. Even removing the patch and restarting have so far not worked. Will see if a reinstallation will do anything. Anyone else having similar problems?

EDIT: Reinstallation doesn't appear to have helped. Pressing "Start Game" has the Steam pop-up screen appear, then nothing...

It's definitely no small feat that they fixed the Italians suiciding their divisions in the English Channel, but I have to admit this diary is a bit underwhelming. At least they are back though and are hopefully ready to start work on the Asian-centric DLC they've mentioned in the past.

delete your pdx \hoi4 folder in mydocs
 
Modifications on the part of ships, this being left aside, Italy loses all the ships when it enters the war in a month, it had to have an option for submarines, to avoid attacks great formations of warships, in missions of hunting to ships convoy.

CL with range boosted should do ok in most situations (at least for the allies) I would have thought. In fact isn't that what they where meant for historically (genuine question)?

From my woozy memory....

Cruisers were definitely a big trade-protection thing for the Brits - less so for the US and moreso for the Japanese though. They also had the role of scouts for the Battlefleet at least in the interwar period. However, the Admiralty's main reason for wanting to build lots of cruisers (which happened to be light, because lighter were smaller until the Brooklyns and Mogamis lead to CL 'inflation') was for trade protection.

I love how your claim your memory is woozy when really I suspect it's significantly better than mine is!

Haha, I promise it really is woozy :) (although whether it's woozier or not I'm not sure how we'd measure! But I read a lot of naval stuff, so even if I remembered more, if I remembered a smaller proportion of what I read I could still have dodgy memory)

That said, the main point of something like that is to try and make it clear how confident I am of something when I'm posting it though, so, for example, if I had to write "The Royal Navy tended to order its destroyers in groups of eight during the 1930s and first half of the 1940s" I wouldn't say the woozy bit (at least right now), as I'm confident of that one (I just finished reading a book on British destroyers :)), but something I read longer in the past (say, on Japanese submarines) would be much hazier, so I'd be less confident my brain had lined everything up well. On the cruisers, the memory is a bit like groping around for something in the fridge with the lights off. I think I've got the milk, but there's a small chance I've got the orange juice instead!

Not trying to sound "Yeah but you didn't do X" but how come we get all these great new leader portraits while Alf Landon and Earl Browder are still using Mr. Wilson as a placeholder portrait?

Put these on the wishlist. Will be done when we have free art resources (so about half an hour before the heat death of the universe, give or take 30 minutes)
