Hello, I'm working on my orchestration exercise, Beethoven sonata no.2 mov 2. The professor wants me to add many dynamic signs which Beethoven didn't write. After finishing the previous 32 bars, I find Lilypond only outputs Ps, even though I set an option to delete ps file. When I check the score, I find many unterminated slurs, phrasing slurs and hairpins, which generate midi error messages. I remember someone referred to the "improvement" that Lily will not warn unterminated spanners any more. This is bad in fact, because I have to search through the whole score to find the unmatched items one by one. Can the warning be put back?
