Have been playing the level 62 amethyst weave and have been experiencing major audio glitching. At high density of hordes (and death orbs), the audio constantly cuts in an out, a few times a second, making the audio completely unusable and very painful to listen to. Typically starts half way through the weave, and only goes away when the number of mobs/orbs depletes.
Was experienced by all players, host and clients.
