I've hit a problem. Most of the time, the mod works, but occasionally the game will only play one song, and then not play any more music. This issue continues until the game is restarted. Additionally, some of the VAB songs sometimes continue to launch. The latter isn't really annoying and might even be intended, but the former is incredibly annoying. I'm using Astronomer's Music Pack, which was linked on the AVP GitHub page, if that helps.
