Unfortunately the crash is happening every time, or at least 90% of the time. The weird thing is, when I initially load up the pack as mods, I am able to exit to main menu without a crash, but if I load it as dlc it'll cause a crash.
As for the music, I'm tempted to suggest there's simply a maximum number of custom audio files Civ can handle- and if you go over it breaks. The Touhou Civ thing seems to disprove that theory- and as an amateur programmer I haven't been able to parse the 9000+ line file for any errors with any success. It doesn't seem like there are any broken tags or lines of code. Would an invalid file reference on one of the lines (say, the leader name is wrong or there's a typo in the music type) break the entire file?
