custom SVGs disappear when reopening a file
yesterday I prepared a file with some oboe multiphonics with their pitches. I created all the fingering for them in inkscape and had a beautiful musescore3 file. Today I opened the file and only one of those SVG images is visible, all others have disappeared. I have tried also creating a palette and saving the images there, but every time I open the file the SVG images disappear. I am very surprised with this and frustrated as there are no warnings or error messages of any sort.
whats going on??
