Big Belly, Eater of Men is broken.

The spawn of the rare hippo, "Big Belly, Eater of Men", is currently broken. Instead of spawning him in Antiquarian and Ascended Antiquarian realms, Sphagumph the rare Galumph is spawning. Now, something in the game is still triggering a kill for Big Belly, as it is possible to complete Fabled Fen Hunter. As an additional note: When attacking Sphagumph in both of these realms a random hippo crossed the zone to attack me. I suspect the spawn may be dropping Sphagumph and a group of hippos instead of Big Belly and a group of hippos. In both realms, there were no nearby hippos to aggro when I killed Sphagumph, and the hippo that attacked was behaving kind of like when I kill any other members of a hippo group.
