The "Add Set's Parts to List" button stopped working for me on Sunday evening. I use a Windows laptop and an iPad for Rebrickable and am getting the same result on both. When I am on a Set Page, all the free functions under "Actions" work except Add Set's Parts to List, which is, of course, the one I really need right now. When I click or touch the radio button, it briefly highlights, and then nothing happens. While fussing around I found that the function DOES appear to work if I am on an MOC page! Any help is appreciated. I hope I provided enough info.
