It turns out that the order of parameters I'd used to specify which draw number page I was regenerating made it wrongly compare the draw number against the maximum allowed main Lotto draw number, rather than the max Daily Play draw number - oops! A quick re-order of params fixed that and the page generation for Daily Play is now working again (yes, I had a missing individual DP page or two for a good few days).
