title: Unity3D Load Level async progress strange behaviour
body: <p>I'm trying to load a scene asynchronously so I can have a nice progress bar and I found that the returned AsyncOperation.progress stops at 0.9. I don't have a problem with that but what is happening is that after that, it takes up to 50s to load the scene and that doesn't show on the progress. After deleting some objects I found that there is 1 (the main scene object) that is causing this delay.</p>
  
  <p>My question is, is there any way to load this object in the first 90% of the load (which is happening super fast right now - 1s)?</p>
  
  <p>Thanks in advance</p>
