I recently submitted my thesis for viva and have since noticed that by transferring from one computer to another endnote has changed my references. The end result of this is that there are 3 extra references at the beginning of the list (which throws out all the other references by 3). Is there anything I can do about this? Are my supervisors allowed to contact the examiners and make them aware? Or do I need to suck it up and face it head on at viva.
