P: Smart previews disappear for modified pictures

I generated smart preview for a entire collection and I can see the "smart preview" and "original picture" below the histogram for all pictures. However it happened several times that when I remove the external disk on which raw files are stored, the smart preview disappear for the picture currently in development. I can check now that I have 16 pictures with smart previews missing, these are exactly the picture I modified in the development module. Is this a known bug ?

    This issue should be fixed in Lightroom 2015.6/6.6 or later.

    We are fixing the issue: that's while deleting a virtual copy, smart preview of the original disappears.

    Thanks,
    Sunil

    Any news about this bug reported 3 months ago ? Smart Previews are almost unusable in my case, very annoying.

    Reproduction steps:
    1. Create a Smart Preview for a photo (Libraries module, Library=>Previews=>Build Smart Previews)
    2. Hide the original file from Lightroom (e.g., rename the original file, disconnect the drive it's on, etc) so you're working with the Smart Preview when doing your editing.
    3. Make a virtual copy of the photo (Photo=>Create Virtual Copy)
    4. Delete the virtual copy
    5. The MASTER photo which was not deleted no longer has a smart preview.

    Smart previews should only be removed when all copies of a photo that could potentially use that smart preview are removed. This bug has persisted across several version upgrades.

    I keep my primary files on a big slow RAID and edit smart previews on my laptop a lot, and often use virtual copies to have one color and one black and white version of an image. Sometimes I decide I don't want the B&W, or just decide I want to go back and create the B&W after making a few more edits to the original, so I run up against this bug a lot in my workflow.

    We could reproduce the behavior. We are investigating it.
    Thanks for pointing this out.

    Thanks,

    Thanks for your diligence and the new steps to repro. I agree that isn't an expected behavior. Let me see if I can duplicate it.

    Sorry for the time it took me to answer, but I wanted to make sure I can reproduce the problem. I can say now it is actually related to virtual copy. Here are the exact steps I just applied which cause the problem:
    - Import the pictures from SD card to hard disk with "create smart previews option"
    - Hard disk attached, create a virtual copy of a picture
    - Remove the disk
    - Delete the virtual copy => the smart preview of the original copy disappear
    - Attach the disk again : the original copy shows only "original image". All other pictures have "original image + smart preview".
