Achievements working?

I was a beta tester when GC4 was Epic exclusive, and there were a lot of problems with the achievements early on, but as far as I know most (but not all) were fixed by the time Supernova came out on Steam and I switched to playing it. As an example, here are some of the achievements I've gotten:

I haven't played on Epic for quite some time, so they may be broken by now.

Hmmm.....

Wonder what I need to do to fix my achievements?

same issue here, Dorian Gray II.

Just installed the epic version and tested it. 

I just used the wingame cheat and I got an achievement popup. Are you playing offline? I'm not sure what could be going on. 

I am playing as I type this.  How can I check to see if I am offline or not?

I launch the game via the 'Epic' frontend.  From what I understand, it has to do some kind of online Epic acount check, etc.

However, it is still not registering any "Achievements".

But I seem to remember that while playing I have periodically received achievement notifications - even as recent as last night. 

After checking, it is only failing to register "Achievements" when using the SuperNova Mod.  hmmm....

OK Devs,

To assist you, I have ran the "TroubleShooting" feature via the Epic Launcher.

No issues found, to include any connectivity issues:

Just discovered that I can obtain a Steam activation key and install / run via Steam in lieu of the Epic Launcher.

Going to try that and see if I have any better luck with SuperNova achievements on that platfrom.

Seem to be getting achievements via Steam....
