Hello, LSR snippet 960 works alright with LilyPond 2.24.3 and earlier. Ly 2.25.1 (and later) aborts with an error message, see below. In the docs I haven't found any changes to the functions in use. Also tried convert-ly, but it did not change anything from the code. Am I missing something or is this a bug?
