Ran into another problem, unfortunately. Whenever I enter combat, the game plays the usual combat intro music, but afterwards, there's no combat music at all. All the units play their usual combat noises whenever they attack/get hit, but there's no background music at all. Once combat is over and I return to the adventure screen, the music starts up again as normal. Bizarrely, if I attempt to adjust the music volume while still in the Combat screen, it starts playing the adventure screen music again. What's going wrong here?

EDIT: OK, I tried playing a different campaign (Shadow of Death) and this one had the combat music playing properly. Maybe the first one was just a glitch? I'll update this if I run into the issue again.
