Vision of the mod
I always love the idea system of EU IV, but soon found it quite lacking in variation. Thus this mod was started. Its scope soon became wider, adding buildings government reforms and new estates all interacting with the new idea groups. What once was a small mod has probably reached the level of total conversation as it is.

What does it mean when it says "reduce development malus for core province" for decentralization?

@Flogi I will. I hate the EU4 mission tree so actually I have been playing on the Japan Update, with the direct dl version of your mod, for years. I recently decided to try the Emperor update and tried using your mod through Steam for the first time with no luck. I'll try the direct dl version when I finish my current game.

How did you mod the custom GUI window for the government reforms screen?
Helios Jan 9 @ 6:27am 
@Flogi : Ty for the answer.

This explains a lot of things.
On the other hand, if we remove all these state buildings, we can no longer rebuild them, suddenly we have to think twice before doing it, especially when it concerns the governor's palace ... But sometimes, that's enough disturbing.

As a result, the bonuses of special buildings like this palace or universities are still not in each province.

Maybe it is better to leave the possibility of building them from everywhere to avoid the bug?

sorry for my bad English

wait that doesn't make sense. that makes militirized society utterly useless.
the whole point of it was to be prepared for war while at PEACE

@nickytheheel: Then I suggest you try the direct dl version.

@Kharnath: By being at war.

@Helios: Normally those buildings should only be buildable once per state. However there sometimes seem to be problems when you conquer a province of the same state that already has a building. With the current engine limitations its difficult to do smth about it.

I have a construction problem with the buildings. Some provinces I can't build universities or courthouses like it matters to the entire region, then other regions I can spam without worry. Where does it come from? :(

how do you get rid of the demilitarisation of state modifier?
nickytheheel Jan 5 @ 8:45am 
Yeah, not working at all for me. With this mod, and only this mod, installed it's just the vanilla game. Sad, as it's my favorite EU4 mod ever and the only mod I consider essential.

I should note this is the only mod that I'm running that is not strictly a UI mod.
