Hi there, this is usually a network or Steam server connection issue and should resolve on its own within a few hours or days. Try restarting Steam (quit it entirely from system tray), you can also try reinstalling the game. Hope this helps!

Hello! Thank you for your reply! I have uninstalled and reinstalled the game, and also restarted Steam too. I'm not sure what else I can try. ;_;

It happens the same to me, and nothing helps TT

I'm having the same issue :/ Reinstalled the game, restarted steam, restarted my pc, waited a week to play again, nothing solved it..

Hi, unfortunately, we cannot recreate the issue on our end, so I cannot help much. Just saw on the Samorost 2 forum, that someone was able to fix achievements by whitelisting the game in their antivirus program. I'd say it is worth a try. https://steamcommunity.com/app/40720/discussions/0/2843417619898771723/?tscn=1706194745

Alt Tab seems to break the game and its menus. Achievements don't work even if the firewall is off. Deleting my save file / reinstalling the game didn't work. It's OK if you can't fix this, I still enjoyed the game.
