Given a choice at viva

S

So, I had my viva and my examiners gave me a CHOICE of R&R and to do more primary research (which I told them did not exist!) in one set of chapters, OR Major Corrections and make substantial changes to different set of chapters… who does that‽
So of course I picked Major Corrections as that meant I passed, and have 6 months to make the changes. Anyone else had such a strange viva?!
