Since the final entry for 41d is certainly in Chambers I assume the preamble is referring to the answer, which isn't, even in the relevant appendix.
I'm not sure what the problem is with 31d. It's a perfectly normal word, not obsolete at all.
Saoralbar, I suspect you have made the same error I did in the bottom row to end up with a non-word in 34d. Take care with the doubled cells.
The final adjustment was only partly what I expected, so I was a bit slow to see it. The position and inclination of a certain thematic word looks right before any adjustment. The adjustment is necessary to end up with real words, but to me it's visually wrong - a slight flaw in an otherwise brilliant grid.
