This new image contained critical data which the old CHD was not made with, so it had to be resourced and reconstructed as a CHD with new functionality in found recent CHDMAN improvements. You'll find that this will be happening quite often in the coming weeks/months as new dumps are acquired. This is not a bug. this is simply an issue of you missing the proper CHD. The SHA1 in the driver is correct. Closing
