This only happens on one album from time-to-time. The only solution is to delete the entire folder from the library and then re-add it. It seems that every now and then, LR just has this urge to stop moving photos. It will move the first 2-6 photos.. and then just completely stop. Progress bar stops and CPU fans start going crazy, but with no activity? The video below sort of shows the issue. What's worse, is that it also seems that LR doesn't even know it moved some photos, which causes all sorts of issues with the actual integrity of the catalog.

What I noticed was that some of the pictures of the ones you selected were missing i.e. LR lost the path to it at some point. Try locating those files first(instead of clicking cancel when the pop-up appears, click locate) and see if you are able to move them after.

They were missing because LR moved the files to the new folder, but failed to notice. All images were in their correct locations, which is why I moved them back, demonstrating that LR finds the images once I put them back in the original location.

Sorry to hear that Aaron. I tried the same workflow and was not able to see the issue.

Could you share more details? Could you open up Activity Monitor when the progress bar stops and send a sample+spindump of the Lightroom process?
Also, could you share a copy of the catalogue (via dropbox/drive) - before moving and after moving? That would help us investigate the issue in more detail and zero-in on the problem.

Thanks for your inputs.
