Rotating/saving a 16-bit image results in an 8-bit image
I have a bunch of 16 bit scanned photo's and some need rotation. But when I rotate them using EoG, it saves them as 8 bit images. This is technically data loss. (Don't panic, I haven't actually lost any data to this bug). This happens to TIFF and PNG files.
