[AssetBundle] When loading prefab from asset bundle "GameObject references runtime script in scene file. Fixing" error is thrown

Asset Loading


Steps to reproduce this issue:

1. Open the attached project
2.Build AssetBundles (AssetBundles->Build AssetBundles from the menu)
3. Load the "Main" scene.
4. Press Play
5. Observe the errors logged ("GameObject ("name") references runtime script in scene file. Fixing!")

This also results in strange errors where MonoBehaviour fields that are initialized in Start() are null in Update() despite never being set anywhere but Start(). See the "How did testObject become null?" error appear in the console after entering playmode

    This is marked as "Status: Fixed in future release"
    Is it be resloved, until Unity 5.0.2p2 I never seem it has been resolved.

    I change the script class name, and the reference to prefab is broken. If I remove the script which missing on the prefab, re-add it onto the prefab, and rebuild the AssetBundle, everything goes OK again.
    I dig into the prefab file and see just the fileID of the MonoBehavior is changed.
    You can repeat this 100%

    I have this error, when I changed MonoBehaviour script to simple ( mean normal that no derived from MonoBehaviour ). So I had that non-monobehaviour script connected to GameObject. That causes error in my case.

    Hi everyone,

    5.0.1f1 update has rolled out since, that fixed the problem for me.

    I'm still seeing this in 5.0.0f4 and can't upvote the bug because it's closed as fixed. Clearly not..
