Photoshop somehow managed to corrupt the save data for the painting I was working on. It was also kind enough to delete all of it's recovery and autosave files! How nice of it -_-
I'm so annoyed by this. I managed to recover some of the painting, but it's hours of work behind what I had. Not sure when I'll finish it. Might call it quits until I can look at photoshop without having the intense urge to throw it in the recycle bin >>'
