I have several photos that somehow got all the placed spot removal that I applied the previous day in different locations, spread out over the photo. I am not sure why this happens, it's my 3rd time. I would reset, but there are other adjustments that I don't want to lose.
If you have the spot removal tool activated, there is a reset button in the panel for the tool that you can use to reset just the spot removal. I'm not quite sure what happened in your case, but you need to make sure you don't have auto-sync enabled with multiple images highlighted when you use the tool. If auto-syncing is enabled then the spot removal tool will be applied to all images in precisely the same locations.
Thanks man. I forgot about that! Yes, that issue is baffling me and many others. If I find the answer, I'll repost for you so you know too.
