When trying to play this map on a mac, I get a terrible, loud 2 second music loop over and over again. It is tied to the effects volume so if I turn it down I cannot hear anything else. At first I thought it was the lobby ads glitching and playing infinitley, but i totally deleted those and the music loop is still there. This is not the map music tracks, those are controlled by the music slider, not effects volume. Please help?
