[2023] Achievement View Bugged

You can see your achievements in the Steam client. Click on this game in your Steam library, and go to View My Achievements.

Is that what you were after?  

I see, then your achievements are run by your other vendor - GoG, Epic, or MS/Gamepass I guess. I'm not so familiar with those platforms but I'd assume they have an equivalent way of viewing them.  

All achievements are triggered in the game and so show inside the game, yes, of course! But Steam ones are indeed managed by Steam which is how you get them in your Steam account.

I'm still not sure which edition you have but for instance the same is true of Epic - they manage them , they are part of your Epic account not Paradox account. You click on the ellipsis in that game in your Epic library, and choose Game Achievements there to see them.

I don't have a GoG account so I can't check that one.  

I thought GoG used their Galaxy as their front end - are you not using that but purely running from stellaris.exe ? In the case of those other platforms that would certainly prevent them from recording achievements.

In any case, I've drifted off from your core issue that the in-game browser is not working in that respect. GoG is the one game version I have no access to so cannot test that; it's probably best to make a new thread in Bug Reports on that issue, if there is not one already, as I don't believe there's anything you or I can do to fix that here.  

We don't have a direct link to the Paradox Achievements page, indeed so far as I know there is no such thing. I've certainly never heard of it in 20 years of working with Paradox. But I know you are going to disagree with me on that, so let's drop it.

If you can get the in-game browser working that is bypass the whole issue, so I still suggest you lodge that as a bug.
