    Having the same problem on Unity 5.1.2f1, I just do a quick trick I made often when I have a problem like this :
    -Quit Unity
    -Delete library folder of my project
    -Relaunch
    -Enjoying again making awesome games !!!

    Not fixed. I file bug reports for things, but never get any traction on them.

    Just happened to me in 5.2.1p2. Definitely not fixed.

    Is this really fixed? I have this every time I do a headless build of my assetbundles. All scripts that reference the UI then go missing.

    In the build log there's this:

    Asset 'E:/Program Files (x86)/Unity 5.2/Editor/Data/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll' is in timestamps but is not known in guidmapper...

    [Assets > Reimport All] solved this issue for me.

    I'm seeing this WAY more on Unity 5.2. Happens to me almost every time unity crashes. Also happened randomly. This is not happening multiple times a day for me.
