Gah, wish I knew how to help with mods. ;~; I remember seeing a notepad file in one of the fh folders, I believe. It was the roar and the howl but I am not sure where I found it. And I think the whole .mp3 vs. The .wav definatly has something to do with it, just gotta make sure you got the right files to match the old ones, and if the length of it is causing it, then I am sure you could find a roar or howl on google that sounds cool :3 sorry if this sux lol, I hope that was of some help though ^^;
