This is a new issue I'm experiencing in Lightroom CC that has caused some grief. After starting to move some images or image stacks, I'll start selecting another set of image to move... but at some point my new image selections resets to the first image right after the other images have started moving to a new folder. I then have to start my image selections again. If I am fast, I can get the newly selected images moving before it resets. On a few occasions I thought I was moving several image stacks but Lightroom has reset the selection to 1 just before they started the move to a new folder... and only 1 stack ends up moved. I do this multiple times a day and on a few occasions I've not noticed that the stack selections reset, so I only processed one image stack from the new folder, leaving the others in the original folder. The next day when I'm delivering the processed images to my client... I'll realize some of them are missing and I'll start swearing at Lightroom for this little annoying bug. Now I have to be vigilant that Lightroom is actually moving all of the images I've selected or I may end up not processing all of my client's images. I either have to wait for Lightroom to finish moving the images to a new folder (somewhere between 2 to 10 seconds) before starting my new selections, or I have to try to get ahead of it and try to start to move them before it resets. When doing this about 20 times a day, this time start to add up and it's another thing I have to be careful of.
