Sun Position not working in Server environment?

I’m throwing SunSky actor in the Collab viewer template(which is server template) and somehow thought it will work magically with no tempering. Hmm

It works just fine in the editor (even in the stand alone play)

But as soon as it’s packaged, it stops updating the sky. (change of brightness somehow still works)

Would be amazing if someone tell me how to make it work in the server!
