After analyzing all the cards fairly thoroughly it appears that the card in slot 1 wasn't written to at all in that session and the card in slot 2 was written to but became corrupt through the shoot. The spare card in the grip was already previously formatted (in the same camera but earlier) and worked fine.
I don't check much during a shoot, just a little chimping at the outset to ensure that I'm not clipping highlights. I have the rear screen turned off and the top screen illumination controlled by the RAW button, so I don't keep an eagle eye on the top panel, I did just expect it to work stupidly. It was dire lighting last night too, I shot the whole show at ISO8000 with the lenses open to f2.8 and barely made 1/100s for the most part, reasonable results IMO considering the lighting but as good as perfect for what was needed by the producers. So all good in the end, had me more than a little stressed though as it was a cornerstone shoot. Thanks for the feedback.
