    Unfortunately I can confirm it doesn't fix the issue.

    I'v also installed 5.2.2p2 and lights still disappear after occlusion backing (I have around 90 active spotlights in my scene, 5 of them cast shadows, andd all of the shadow casting lights disappear in game view after occlusion baking)

    There are indications that the fix for this situation may not have resolved the issue.
    See the related thread:

    When installing the version of Unity 5.2.2p2, which listed this issue as resolved, the issue occurs again when adding additional lights to the repro scene.
