There's a missing file bug that says I'm missing audio/bgm/party.ogg, which pops up every few seconds after it first happens. It starts during the cutscene leading to the first scene with Scarlet in the sub route, right after the black screen after her drinking contest with Shaun but before the drinking contest with your character. Starts a few seconds after Scarlet says "And another one bites the dust." I've tried just throwing a short, silent .ogg file renamed to party.ogg in the audio/bgm folder, but it didn't fix the issue.
