Invalid SceneHandle

Hi all,

So recently, I have been receiving strange errors when running a release built version of my game.

 Invalid SceneHandle
 
 (Filename: C:/BuildAgent/work/b0bcff80449a48aa/Runtime/Camera/UnityScene.cpp Line: 283

This is the error from output_log.txt. The error causes various textures and models not to be displayed on the screen. It should be mentioned this only occurs after calls to Application.LoadLevel(1), and that this call works when used in the editor.

It has been previously mentioned that this could be related to NGUI, which I am using to build menus.

 Unloading 3 Unused Serialized files (Serialized files now loaded: 0 / Dirty serialized files: 0)
 
 Unloading 9 unused Assets to reduce memory usage. Loaded Objects now: 526. Operation took 5.453607 ms

These two lines also appear suspect in output_log.

Thanks for any and all help.
