I've been doing battle with this all week, I'm down to the last two clues to solve and I'm all out of ideas - please could somebody take pity on me and give me a shove in the right direction?
I'm fairly certain that both need part of the answer exchanging for a punctuation mark, I could be wrong though!
12a plant design lacking compliance
18a uprising is terrible (not in the end)
Thank you very much!!!
