Yes, oddly I had transposed the last two letters of 10a. I could see what needed to be done with the first two words of 7d so was looking for an odd word.
This solve was split by a trip to Murrayfield. Never quite felt like I'd broken the back of the puzzle until there were only three left to solve. LOI was 26, if I'm correct here then it's not a word I've used very often if at all. Maybe my brain is just struggling.
I like puzzles like this, where it feels like a struggle, but you make progress enough and a review shows that everything was perfectly fair and it just had you stumped.
