yeah it’s bugged with every instrument, you just got lucky you didn’t run into it the first two times. you can return to the menu and try picking it up again. I suspect it has to do with the dialogue. try going through it faster or slower. alternatively you can edit your savefile. open save0 and add a line s object<whichever next highest number> instrument2:1. instrument2 relates to the 3rd instrument (it’s an index). maybe you can progress that way.
