I had to take out the ufo2 track. It was just too loud, too frequent, and began to grate on my nerves when I'd have to hear it looping for ten minutes while I worked on my soldiers' gear and stuff. However, I think it's going to be necessary to put a file of some sort in its place because my game crashed today, total lockup. Couldn't even drop back to desktop. Ironically, the crash happened right after I downed a UFO and was prepping a ground assault to go pick up the pieces.
