Found this one difficult and have a problem with the final letter to 13a and the third letter of 11d, I have Fata Morgana for the former and Amedeo Mod. etc for the latter and can't find any evidence for alternative spellings, any guidance gratefully received
If you want to submit your grid, I'd draw a diagonal line in the light - top-left to bottom-right - & put 'A' in the left section, 'E' in the right. Assuming they don't void the whole puzzle, that would show you have both correct answers.
