I nearly abandoned this with 5 clues left to solve but have now finished with a couple of queries. Great construction by the way!
17a I know the answer, the definition and the word removed but just can't see the wordplay.
29a I can only make the overall 'helpful' content work if I omit a word that's longer than the 2 letter word that I originally omitted (spoiler earlier in the thread). However, that spoils the wordplay for the clue.
I also haven't spotted the 5 across and the 5 down words that hint at who was responsible (although I know who it was).
