In an attempt to duplicate what you did I started a new game, added board 10, flipped it, cropped it to r-ff & clicked "done." I then added a new row, selected board 23, flipped it, cropped it to b-p (remembering to select board 23 in the drop-down) and clicked "done." I did not have any issues. The result was the same as adding both boards at once. Is there something that you did differently?I think the issue was I was adding one board at a time and trying to crop them rather than adding them both and cropping them together. It wouldn't allow me to crop the second board after the first was done.
