Congratulations to all you clever guys who've already finished- light years ahead of me!
I've been thrown by several entries that don't seem to make sense eg in 30d, I have a good answer, which , with a misprint, makes sense too, but the replaced letter isn't in Kea's list. In 9d, another good answer, but there's a flaw in the parsing.... I'm basically stumbling around looking for anything that may work!
