Hi everyone -- the fix for this seems to be to verify your installation, and then to restart Steam (in that order). Please let me know if that doesn't resolve your issues!

Hello!
Gary from Abrakam Entertainment here.
Last week[forum.paradoxplaza.com] we talked about what Astral Rifts were, how they were formed, and what you could find in them. We also briefly mentioned something nebulous about a new resource called Astral Threads and what you can do with them. We call these, simply enough, Astral Actions.
Let's dig a little deeper.
Astral Threads
Conceptually, an Astral Thread is the material that binds the boundaries between dimensions. In areas where these boundaries are weakest, these filaments of existence unravel to the point at which they become tangible objects that can be harvested. This unique resource can be put to various uses should you possess the proper technologies and level of attunement to the Astral Planes.
You'll first be able to gather Astral Threads when you encounter an Astral Scar, which you'll remember from our last post are minor tears in space-time present at map-generation. As when discovering other rare resources such as Dar... Read more

Hello!
I'm Gary Morris (or Atmaz) - Lead Game Designer on the Astral Planes DLC, from Abrakam Entertainment.
I've been playing video games my whole life. Some of my earliest memories are staying up way past my bedtime and grinding out hours and hours on strategy games on the Super Nintendo my older brother got for Christmas. I have specific memories of a particular game where I was cleaning up nuclear waste with my workers, tile by tile, and having a great time doing it. I didn't know it at the time, but I was enthralled by a type of game that would later become known as a "4X."
When I finally did get a computer, it was a Tandy 1000 HX. I still don't know what the HX stands for, or what the fascination is with adding X's onto things. On that machine, I quickly acquired a similar 4X game that was much older, but it captivated me just as much. Its lack of fancy graphics was not a problem for me, because I was given a very powerful new tool to play with: a keyboard. In my blissful ig... Read more

Hello all,
We're proud to release the 3.9.3 "Caelum" Patch promised for mid-October. This patch brings with it a balance pass on subjugation and diplomatic acceptance in-general, as well as other balance changes, bug fixes, UI, AI and modding improvements.
Please find the patch notes below.

In this week's dev diary, I am taking the reins from Eladrin.
I am a producer on Stellaris and usually help Eladrin as best I can, but today I want to talk about my other project and let Stellaris have a week off before they talk about their next thing.
And that Project is: Star Trek: Infinite

Watch the video version of this Dev Diary
Who are you? And why are you Putting Star Trek in my Stellaris Dev Diary?!
I joined Paradox back in the start of 2021, and was given the task to bring Star Trek: Infinite to Launch.
Today is that day: we launch Star Trek: Infinite.
Why am I talking about Infinite in the Stellaris Dev diary? To start off, I am a producer on Stellaris, but also the producer for Star Trek: Infinite - I love playing both games, and I think some of you might feel the same.
Secondly, as all of you can easily identify, Star Trek: Infinite is built on the Stellaris Engine, with little effort to hide it. Everyone here on the Stellaris team ... Read more
I'll pass this along to our teams. <3

Hello everybody!
Today we’re going to look at a likely 3.10 feature, some changes that we’ve called the Leader Consolidation.
With leaders becoming more important to your empire following the 3.8 ‘Gemini’ release alongside Galactic Paragons, there were some rough edges leftover and experiences that could be better. Some of the changes we’re implementing during this leader consolidation were things we talked about during the development of Galactic Paragons but decided against for various reasons, or were out of scope at the time, while others are based on data gathered since then and community feedback.
So What’s Changing?
Some of these names are still being argued over, so are subject to change. Hate one in particular? Let us know. One of us probably hates it too.
Admiral and General will remain as veteran classes, with the following foci:
- Admiral - Focuses on Fleets and general naval combat
- Genera...

Hello all,
The latest minor patch for Stellaris is ready and released, fixing a number of issues and further balancing the new mechanics.
We're also planning a follow-up 3.9.3 patch for mid to late October, which will include some of the issues brought up during the Open Beta that require new text, more fixes that did not meet the 3.9.2 deadline, and a handful of other improvements.

Hi everyone!
It’s been exactly 100 dev diaries since we introduced the Custodian initiative[forum.paradoxplaza.com] alongside the Lem update. With that milestone met, and 314 being funny math number, I thought it would be a good time to review what the Custodians have accomplished, some of the process they use, and where we could go from here.
To review, the original idea behind the Custodians Initiative was to do some of the following:
- Tweaking game balance
- Adding new content to old DLC
- Polishing existing content
- Bug fixes
- Performance improvements
- AI improvements
- Multiplayer stability
- UI and quality-of-life improvements
So what have they accomplished so far?
In my view, the Custodians have been a pretty solid success.
We’ve done a few things:









I promised bad math jokes last week: Why did the Blorg cross the Mobius Strip? To get to the same side.
So how do the Custodians work?
Ideally, a third of their tasks are dictated by my directives, a third are taken from community requests, and... Read more
Users with this issue, can you advise what (if any) mods (especially UI mods) you're using? We're trying to narrow this issue down. Thanks!

Hi all!
The Stellaris 3.9.1 ‘Caelum’ update has been released, with full release notes listed here[forum.paradoxplaza.com].
Unless critical issues arise over the weekend, our current plan is to have a general bugfixing 3.9.2 patch roughly two weeks from now. We’re also planning a followup localized 3.9.3 release in mid to late October, which will include some of the issues brought up during the Open Beta that require new text, more fixes that don’t meet the 3.9.2 deadline, and a handful of other improvements.
What’s being considered for 3.9.3?
Localized updates are the only time we can add new text to the game, so some of the suggestions made during the Open Beta will be included in it.
Agendas will now show the required time to enact.
We’re also making some upgrades to the existing recommended DLC screen. To make it more generally useful, it will be possible to see things like the tooltips of origins and find out what’s actually in this thing?... Read more
