New skybox visible in Editor, changes to previous skybox in Build

Hey guys,

I recently changed the skybox in my game, and in Unity the new skybox displays perfectly. However, when I build the game it switches back to the prior skybox I had. Not sure what the issue is or what information to give, hope you can help me out.

Thanks

Only thing that comes to my mind is saving the Project and the scene. Otherwise changing the skybox of a game should always work just fine.

Did you found the wrong?, I have similar problem,
Thanks.
