Okei, I've tried 100 of times now trying to swap Black War Mammoth into Amani War Bear.
But it seems like there is a problem, cause in the ModelViewer there exist 2 MammothMountBlack one for alliance and one for horde it has the exact same name and same with Amani War bear, it's named BearMountSkinBlack and there is another mount named exact the same, so it looks like they share item ID's, so if you know how I can do this please tell me or if u are kind enough. Make me this swap and I'll return a +rep to u.
