I don't see how this could happen. Are you sure it went through the whole imaging process?
I've had a problem before where after changing the name it didn't image and went to a boot error. Had to delete the whole script and remake from scratch.
it seemed to complete the capture process successfully - I have a task entry to restart following the capture & the image seems to be the right size.
Plenty of space left on the net drive where the images are stored also. Perhaps it is just the Provisioning task that needs to be recreated after a name change... Still trying to set aside some time to test.
