P: "The file appears to be damaged" - Merge To Panorama with large Canon 5Ds files.

I am attempting to create high resolution HDR Tilt-Shift Panoramas with Lightroom's Merge To HDR and Merge To Panorama functions. I have taken multiple images with a tilt-shift lens on a Canon 5Ds. Each finished photograph would be composed from 15 or 21 separate images. I take 5 or 7 photographs, 1 stop apart, from the center position then 5 or 7 from the shift right position and the same from the shift left position. Each set of 5 or 7 is merged to hdr to create one dng file. This process works fine. The resulting 3 hdr images are then merged to panorama which completes successfully. When I switch to the develop module or open the panorama file in camera raw I get a message stating "The file appears to be damaged". I have reproduced this error on different computers. My Lightroom version is the 2015.4 Release and Camera Raw is v9.4. Both computers are running Windows 10. It seems to me that Lightroom is struggling with the large file sizes coming from the 5Ds. Has anyone else experience this issue.

    The error is because LR cant make a normal preview, thats all.

    True, but it's annoying and I can't tell if there is no error for sure. 

    I tried to export the DNG file as DNG file, reimport the new DNG and there is no more error message. Or alternatively stitch the images in CameraRAW.

    I am dealing with the exact same issue (using the exact same camera and process).
    But it seems that you can just ignore the warning and keep working on the files and successfully export them. So i guess what Lightroom is saying is that the file only APPEARS to be damaged when it actually isn't. Thanks Lightroom for letting me know....

    Yes. This is exactly it. They need to concentrate on performance and stability.

    It might sound strange, but this is actually a feature of Creative Cloud. Lots more updates, but ones that fail to address the biggest existing bugs whilst also introducing new ones and reducing performance yet further. And the best bit is that there is absolutely nothing any of us can do about it because we are now trapped subscribers.

    I'm actually also merging files from a Tilt/Shift lens on a 5DMkII, same situation as thread opener.

    Why does it always feel like every CC update just results in us all having to play 'find what's broken now' as opposed to any actual improvements.. and then the inevitable weeks/months of waiting for a fix (healing brush, liquify tool and now this).

    I'd trade one stable high performance release over regular updates with 'new features' if they are the only two options these days.

    Hoping it will be fixed in the next update.
    But knowing it won't be.

    "image appears to be damaged" after putting together a panorama from 3 Hdr's (also created with LR!). Does not appear (sometimes even then) only when using the same tool directly in CameraRAW via PS.
