To reproduce:
1. Open users attached project "TestProject.zip"
2. Enable Development Build
3. Open the built project
4. Press Assets/Test.1.unity button

Expected result: scene is loaded
Actual result: getting
Scene 'Assets/Test.1.unity' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.
To add a scene to the build settings use the menu File->Build Settings... error

Was unable to test on iOS device, only getting a black scene.
Can not test on 5.6.x because of the C# 4.0 errors
