I replaced all of the mission musics in the music folder ones I exported from audacity, but they don't play in game at all! There's just suddenly no music in the missions. Ones I didn't replace do play though. I tried to export as both 32 bit and 16 bit signed WAVs, no difference. I don't think putting them in a mod would make a difference (I just replaced them for the path of least resistance, the mod system looked complicated) since it just seems the problem is that Door Kickers has a problem loading/playing them.
