Asset Bundles show in Editor, but not on camera.

I've been working on an iOS project and the first screen is a menu with a list of items. When a menu item is selected, an asset bundle is downloaded, then the game loads a new scene. After the scene loads, the previously downloaded asset bundle (a model prefab) is Instantiated into the scene.

The problem is that the asset bundle will show in the editor, but the camera will not see the asset bundle. I'm positive the camera is facing the object and it's loaded into the scene.

In the asset bundle building process, I've specified that the BuildTarget is iOS. I can't think of any other reason why this shouldn't work. Has anyone ever seen this?
