All instruments change to piano upon upload

I have uploaded several scores with no difficulty, but now when ever I upload, all the instruments change to default piano. Percussion also. I do have other soundfounts, but I've made sure to only use sounds from the current Musescore 2 soundfount. I made no other changes to my computer, although I did mess around with the 'Save to Score' button in the Synthesizer window. My glitched score is https://musescore.com/user/1566836/scores/1046166
