Well, I thought that was pretty fierce. Starting to feel confident after two weeks of completing the prize before I looked at the forum, to get almost nowhere this time! Still stick on 23d and 27a, despite the hints here. In fact a comment on 23d only made it worse for me, it suggested that following Nov 31 should have 0 instead of 1, but I reckon it should have a 2 so I can't make any sense of it at all
