Jono I was wondering if this was the same grid again, (the one with all letter lengths from 3-10?). I love that you are interested in grid patterns and even have a favourite. Also thanks for going back and finding where the previous recent occurrence of 1d was.
Lucertola - yay for you! And yes, “was” is definitely a crucial word in 24d and I should have worded my hint accordingly. Sorry for typos earlier I was heady with excitement having completed the Prize, albeit with hints and used the crossword solver to help get a couple of the answers.
Luko it must have been so fun having in-person crossword solving company in the past (something I never experienced) and I’m so glad you have found this wonderful community.
