Last night at about 10:30 PDT the server went down, kicking me back to the character select screen. I couldn’t connect again; it said to wait. I logged back in today, and I apparently lost all progress I had made in the Tomb of Akarat during the quest All Good Things, including the fight against the wolf aspect.
The game doesn’t save quest progress nearly as often as it should. This is the third time I’ve lost quest progress upon logging out, and this time I lost nearly an hour of main story progression. Very disappointed with the VoH launch.
