    I am getting this with a new project as of 4/9 with Unity version 5.5.0f3. It happens at run-time right after this line is executed:
    SceneManager.LoadScene( SceneManager.GetActiveScene().buildIndex );

    The scene reloads, but everything is dark and the error:
    "Error adding Enlighten system data: <large hex number>. RadiosityData is missing."

    This issue reproduces for me 100% of the time.

    Turning the 'Directional Mode' in General GI to 'Non-Directional' will solved the problems for me !!

    Experiencing this as well. I've disabled "Baked GI" in my scenes because of another bug and it resulted to this bug? hmm...

    It is apparently (I've not checked) fixed in Unity 5.4.0, which is a beta release right now. It's supposed to be released next month.

    why is this marked as fixed?

    do i not have the most recent unity version? 5.3.4.f1 (says its the most recent)...

    GI output for inputsystem: 69c802c3543fd2cafe35275b1687c166 (a5c047dd79b2a9d0f1885eb733ec6b26) is missing.

    Error adding system: Data not available.

    this mostly started when i started tweaking and trying to fix lighting... editor and build were completely different... i changed a bunch of settings and made it look good but now i have this popping up all the time...

    I just noticed this error as well while I was modifying my directional light to be the same in three scenes. Now, I also changed a GameObject from one prefab to another, without replacing it in a script (as a "public GameObject player;"). I just fixed that issue and the error stopped. I'm not saying this is a fix, but it might give you a clue.

    I'm using version 5.3.2f1 and got this error. Fortunately this doesn't seem to affect my project in any way, but it still bothers me to have an error on the console...
