Hello,

My achievements progress is stuck at 21% since few days.
I unlocked some new achievements, but the progress is still stuck at 21%.
I even got the message "reached 25% achievements"

My Gog client is updated (2.0.72.94 - Beta).
By the way, it seems weird I got a beta version O_o

edit: it is related to gog client.
The progress is ok in the web page profile

Have the exact same situation here.

Me too

I disconnect my account, uninstalled GOG Galaxy client.

Then I deleted any folders named "GOG Galaxy" or "GOG.com":
C:\Program Files (x86)\
C:\Program Files\
C:\Users\[My Username]\AppData\Local\
C:\Users\[My Username]\AppData\Roaming\
C:\ProgramData\

(And also on my D: and E:)

Restarted my computer

I download latest GOG Galaxy client installation folder, install it.

But still got the issue :(

For me, the issue was before 2.0.1
(I started to play at 2.0.0)

Yesterday I tried to start from a fresh start.
Today I unlock an achievement, and now my progress is at 0% in my GOG client.
And my profile in gog.com returns a 500 error :'(

Edit: it seems it was a tempory bug, my progress is back again at my 21% stuck

I opened a ticket yesterday. I don't know if they already look at it, but today I unlock an achievement, and my progress is now fixed!

I don't know if they did something or if the new achievement after the clean install fixed the progress.
