The .exe in the WindowsNoEditor is not showing achievements in both cases, with spacewar connection and without.
Greenlit or not-yet-released issues should not matter here, because the .exe and the project are both set up for the test id 480, which only purpose is to provide achievements etc. testing before you actually have a game released.
(the .exe is the shipping built of the project, therefore the the WindowsNoEditor folder name).
Wrapped in one sentence: steam all set up for 480 works in stand alone started from the project in the editor, but it does not with a shipping built from the exact same project.
