Realtime GI file not found errors displayed when upgrading project to Unity 5.2

Progressive Lightmapper


Open attached project in Unity 5.2 and you will get lots of errors like:
Failed opening GI file: 'b2/b2d0e671c9df0fff370993e25d0ff60c.vis'.
Failed opening GI file: 'b2/b2d0e671c9df0fff370993e25d0ff60c.rsc.sse'.
Failed loading system data for hash: 0xb2d0e671c9df0fff370993e25d0ff60c

Opening the project in Unity 5.1 first, doesn't give any of these errors, it's only when imported in Unity 5.2

    Aber upgrading to Unity 5.2.1f1 yesterday we do have a similar issue with 2 errors appearing in each upgraded scene:
    Failed opening GI file: 'd8/d80fb6973c8a9c89954149fec3547356.rpc.sse'.
    Failed loading probe set data for hash: 0xd80fb6973c8a9c89954149fec3547356

    Is it really fixed in 5.2.1?

    I have (probably) the same issue in 5.2.1f1

    Failed opening GI file: 'ea/eac2323a2ac7d8b3f624d56e7ef5ca7d.rpc.sse'.

    Failed loading probe set data for hash: 0xeac2323a2ac7d8b3f624d56e7ef5ca7d

    Error building Player: Couldn't copy player GI data for scene 'Assets/-Scenes/scene_garden2.unity' into data folder 'mainData'

    (Mine lightmaps were baked in 5.1.3)
