HOI4 Dev Diary - 1.5.2 Update #1

Hi everyone! I hope you are enjoying Waking the Tiger :) With the 1.5.1 patch released last week the team has now started on 1.5.2. Today won't really be a big diary, but I figured we could highlight some of the changes every week as they are done rather than have a diary break while the patch work is ongoing. The idea is that 1.5.2 will be available as an opt-in beta on Friday (barring QA veto), but we will be rolling out updates to it until its ready for release. Real release is at least 2 weeks away.

Making organizing commanders easier
People seem to really like our fantastic future tech dubbed “Drag-and-drop” (pending trademark registry), so based on community feedback we have decided to implement this in more places. You can now reorganize your armies and army groups by simple dragging them around (we are working on a similar thing for the theater overview to allow it there also).

XP gain on commanders and divisions
There have been a lot of conflicting feedback on how fast your commanders level up and gain traits. Some say it’s much too fast and some say its prohibitively slow. We did a quick fix for 1.5.1 to try and smooth out the progression curve, but realized we really needed to do something more radical. The issue is that its very playstyle dependent since XP is rewarded for every hour in combat. This essentially means that if you play well, pull off encirclements, use concentration of force or overrun the enemy you get very little XP compared to someone who is just throwing bodies at the enemy to slowly wear them down. To deal with this we are changing how you gain XP:
  • Overruns (blocking retreating enemy paths) and shattered divisions (enemy that cannot escape) gives you a flat xp reward per unit that is destroyed.
  • The rate of XP gain per hour is reduced over time with max penalty at 1 month long battle (-90%)
  • The more damage you do relative to the enemy the better XP reward you get to compensate for those combats being relatively short (up to a 4x difference)
Hopefully these changes should help balance the radical differences between long and short battles and reward players who play smart while not negatively impacting the brute force method too much. We’ll be relying on feedback on how this feels during the open beta process to see how it pans out.


Multiplayer desyncs
Looking at statistics from our backend 1.5.1 seems to have improved things and it’s now back to the same level as before Tiger was released. However we still see reports, so we have developed some new tools to help us as well as potentially fixed more cases. We are hopeful about improvements here as well for 1.5.2. Again, we’ll be relying on feedback in the open beta later for this as well.


Doctrine cost changes
With the infamous doctrine-swapping-for-free exploit gone we felt that the cost of switching was perhaps a bit too high now, scaring people from changing up things. To make that a fairer choice starting level of land doctrines now cost half of what they used to (so in line with other techs), making a switch still a serious tradeoff you need to think of, but not as delaying is it is now. The reason it’s not just free is at the heart of HOI4. You step into the shoes of the nation at a historical point in time, so you should need to deal with their current situation. Switching army wide doctrine is one of those things, just like division templates or low war support or stability.


Polish and German border changes
Though some effort was made to adjust states to make german historical WW1 borders possible, as this thread shows, things were still not completely up to scratch. I (Bratyn) decided to put in some of my personal development time to brush up on my map-painting skillz and improve upon what we had already done.

1. The two Polish provinces slightly south-east of Danzig, 6347 and 6321, which previously formed a weird protrusion into Prussia, have now been reshaped with a more east-west horizontal border, with the northern province (6347) being added to the Danzig state. Once Danzig is taken by Germany, this now creates proper borders for Eastern Prussia.
2. I made a minor adjustment to ‘flatten’ the border in the little bit jutting out around Strzelno (I felt it was too pronounced).
3. The two Polish provinces on the tip of Silesia, 506 and 6464, have been reduced in size and remodeled, with the freed-up space going to the provinces around them, as well as a new province (13205) created for the Krakow state. A new state has been created (“Voivodeship Silesia”), to which provinces 506 and 6464 have been added, making it possible to transfer this state via events to Germany, much in the same way as is already done with Poznan and Danzig.
4. While I was at it, I figured I’d fix a personal pet peeve, as well. I reassigned provinces to states all over Eastern Germany, ensuring that the borders between these states now follow the Oder river. I also redrew the borders of the provinces (3514, 3572, 6595, 9535, 11415, and 11517) to follow the Neisse river (which is not shown on the HOI4 map), as well as those of province 6282 (Stettin). This now makes it possible to recreate proper modern-day eastern German borders, for those of us who enjoy that kind of thing.

All of this also involved relocating some industry, air bases, and population from certain states to others, but this should not have much effect on gameplay. Unfortunately, the end result does mean that savegames will have… An unfortunate gap in the map where Voivodeship Silesia is located. Starting a new game when signing up to the Beta or when switching to the patch is recommended, as not doing so may result in some weird stuff (such as units present in those provinces beforehand being perpetually stuck there). This is also the reason why we tend to be conservative with making map-changes, and this is unfortunately unlikely to change.

Glorious end result:

Hats! The people want Hats!
In our ongoing efforts to increase the number of great hats in the game, we have decided to add Paul von Lettow Vorbeck to the German lineup. Best known for his campaign in German East Africa during the Great War, von Lettow-Vorbeck is available for recruitment through a decision after the Kaiser has returned. Given the terrain he fought in during the war, we decided to give him the Jungle Rat trait as well as a pretty good logistics score.

There are of course also a slew of smaller change and fixes we have had time to do, but we’ll leave that for the eventual changelog. If your pet peeve was not mentioned check out last weeks diary covering the main areas we will be working on as this diary was to highlight stuff we had already done.

Next week we will have another update as well as showing off a really really cool thing for modders we have been working with on the side. Stay tuned!

hey @podcat this looks good i just registered to ask if you will release the battleship cosmetic dlc that people have been seeing on dev streams, and also you should add a new state for picardie so that pays de calais is split in half and the reichskommisariat belgien has correct borders, thx
This is the one you get for free if you log in with your paradox account ever since release. I heard there might be some issues there tho. Did you try it?

@Bratyn you're the man, man!
I think "Polish Silesia" or simply "Katowice/Katowitz" would be a better name though.
 
All changes I like. Especially the xp one. I ended up fighting the Allies, Commies, and Spheroids from '38 to '50 and I didn't have any commanders level up except for my 2 field marshals. Even then they only went up 1 level each.
 
If we're redoing the Polish border, is there any chance of making Danzig a seperate state from Pomerania? Many mods that modify the map already have it as a seperate state even if it isn't represented as its own independent polity. Both would still be significant population-wise.

German demands were for Danzig itself with a referendum in Pomerania including all those who had lived there previously. Gdynia and Danzig were also their own huge ports, the former being even larger.

Question about XP: I like to play with historically army sizes, and only make armies of 9-12 divisions. Will this reduce the experience gained on the commaders by roughly 50%?

Because it does feel quite slow in 1.5.1. I have 20 armies going in 1946 and cleared up Europe and soone Soviet. And on my 20 generals and 5 field marshals I 2 terriain traits gained.
 
btw does anyone know what dlc015, dlc016 and dlc017 are? i don't have those either, but maybe they don't actually exist, idk

Fully agree.

@Bratyn This man knows what he is talking about, he has produced more quality modding content regarding Poland than the whole HOI4 community combined.

I also have to ask: Does the new state get any resources? Majority of general historic area of Upper Silesia's industrial capacity was located there.
 
As a more casual player, I'd like to point out that the new leader trait screen is very unclear.
Here are all those cool looking options, and none of them are clickable. I can't choose new traits even when the nice tiny plus sign appears next to a leader's portrait, and have no idea how to unlock any of those nice traits.
This system pretty much convinced me to get the DLC. I expected some progression tree for generals like in Total War games, but instead I get to upgrade one trait per general and 2-3 per marshal, once, for an entire playthrough. It becomes a feature to ignore, rather to appreciate.
 
Any fix for ussr not being able to take occupied allied territory at the end of the war with the axis? You could do this before the new war system but not anymore. It prevents a historical communist poland and creates an allied blob in the middle of your faction's territory.
