I think you need to re do your ETOPS course.
But I agree it is a incident worthy of investigation.
I had a similar one dispatching on a single pack which unsurprisingly overheated at FL330. We were lucky to be able to descend rapidly enough to avoid the rubber jungle and were close enough to destination to make it there. The pack cooled down and lower demand at FL100 meant it worked fine to landing. In fact we kept it from the pax too as cabin alt was kept below 10000'. Nobody mentioned it until de-boarding when one, just one, pax questioned why we did an unusually early descent!! That was investigated as a serious incident.
