Unfortunately not much more to add than the title. Ran an update for the Fall of Plaguestone Module, and when I went into the game after the update, all my music had been wiped from the game. Luckily, it was all still in the My Audio interface, so I could re add it easily. I tried doing a rollback to undo the update to try and capture a console log/more information, but it appears that the update cannot be done again after a rollback (I'll post another bug report for this).
