So I was doing Grub on my level 22 toon, and got to Grubb and died. While quickly healing outside, the game crashed on me. When I logged back in it said I could return to where I left off. Except everything had reset with the exception of the defeat Grubb as my assignment. So I could not go through any of the phases. Ended up just logging out of the game and will have to restart this dungeon. Not very happy about this.
