I can't reproduce this issue. Even if I did, the window.reload way of updating the app state is not correct.

@jelveh These two lines:

$('.new-app-modal').get(0).close();
window.location.reload();
actually address a different issue that has already been fixed: resolve issue #983 - Stuck on "Creating new app" loading screen.

I had already submitted a pull request for this, and it was merged. However, when cloning the project, I couldn't find these modifications in the codebase, so I added them directly to resolve both problems simultaneously.
