There is something wrong with the diode in my schematic or PCB. Please open the PCB at the below link. Press Alt + I or click Design > Import changes. Apply the "change". Now press Alt + I or click Design > Import changes again. Apply the "change". Exactly what has changed? You can spend all day doing this if you like; there's something wrong. Can anyone tell me how to fix it? Thanks very much.
