For some reason all of a sudden, what i've done for years isn't working. When i'm in the develop module and I want to make a virtual copy, it appears to be making the copy and showing "1 of 2" when you hover your mouse over the image, but it's not "adding" a virtual copy in the strip at the bottom beside the master photo. I've tried "unstacking them" but that doesn't do anything either. I've double checked that I don't have any filters on, and they are all clear. I am not working in a collection either. What could be causing this???
Make sure the sort order is either Capture Date or File Name
it's on capture time
