My 18D begins with the same letter as 13A...perhaps the execution of the theme proved more difficult than the setter anticipated hence a bit of repitition.
Our posts crossed peterm...thats interesting, I've already had to backtrack once with 9ac, had another completely plausible answer(until I tried to transmute it)
I don't think I'm as advanced in the NE corner as you are. I haven't got 6dn or 13ac yet. I also can't see the transmutation for 11ac. But I'm happy so far with 4dn and 16ac - but it could change!

for 13A you need to get someone to fashion you a thinking cap (hat), after mutation
as for 11A I have a choice of three mutations but 6D will confirm when solved.
cheers
I'm about halfway through, but it's so frustrating when you're talking about, say, the NE corner, and about the few ones I have done. Is nobody struggling with 7D and 9A? I've done the rest in that corner.
