Gloom shrine explosions cause buffer underflow crash in PvP

In both 1v1 duels and in 3v3 CTF instances, anytime a character equipped with a Gloom/Massive Screams of the Dessicated (and a Gull, if the shrine effect matters) equipped killed any entity (other players, or even worms spawned from flasks) anyone nearby experienced a "Buffer Underflow" error.

After acknowledging the underflow error the game crashed to desktop.
