Achievements no longer unlock since October 19, 2025 (NW.js v0.100.1 + Greenworks v0.21.0 + Steamwor

Hi everyone,

I’ve been using NW.js v0.100.1, Greenworks v0.21.0-nw-v0.100.1-win-64, and Steamworks SDK v1.62 with my Construct 3 (r449 LTS) project.

Everything worked perfectly — Steam overlay, achievements, stats — until October 19 2025.

Since that date, the Steam overlay still works fine, but no achievements trigger anymore, even though the calls appear successful (no console errors).

What I’ve checked:

✅ steam_api64.dll and greenworks.node are present and match the correct versions.

✅ steam_appid.txt is correct.

✅ The overlay shows up properly (so Steam API is initializing).

✅ Calling RequestUserStats and waiting for OnUserStatsReceived still returns true.

🚫 Calling ActivateAchievement("FIRST_WIN") followed by StoreStatsAndAchievements() no longer unlocks the achievement in Steam.

🚫 No error is thrown in NW.js dev console.

What changed:

I didn’t modify anything on my side — same build, same versions.

It suddenly stopped working around Oct 19 2025 (possibly after a Steam client update?).

Environment:

NW.js v0.100.1 (Chromium 137)

Greenworks v0.21.0-nw-v0.100.1-win-64

Steamworks SDK 1.62

Windows 10 x64

Construct 3 r449.9 LTS (NW.js export)

Question:

Has anyone else noticed that achievements stopped working recently (mid-October 2025)?

Could this be related to a Steam client update or a new requirement in Steamworks?

Do we need an updated Greenworks build, or is there a known workaround?

Thanks in advance for any insight!

So to answer your question, RRPG, in my experience, I once had this problem and it probably does have something to do with steam, seeing as you didn't change anything about the game itself. you should contact steam about this though, bc I'm not an expert.

Has anyone heard anything from valve about this? I'm also having issues with Steam achievements not proccing in my game too!
