I imported a piece of music into a map, tested it and it worked. But after, when I tried to play the sound in the editor, it said it did not appear to be a valid sound file. Whats going on? :\
Apparently there's a bug where using it ... *Decides to be blunt* f*cks up your sounds and whatever imported stuff is contained in your map. You'll need to re-import them all and test it without using the Test Map button.
