The last letter isn't "i" : you've spelt the disease wrong.
In 34dn I was taking the first letter of "rave"to be the misprint. I'll have to look at the poible solutions agin if it's the 3rd letter.
"Possible" solutions that should have been. I'm fairly sure that the name is that of the discoverer of new facts about the ten-letter site which surrounds the centre in a ring.
I can't see any at all so far : are the solutions in contiguous cells? At least I've finally solved 34 down : a very obscure use of the misprinted definition: Shakespeare and Spenser have a lot to answer for..
