So I was playing earlier and I had just finished a quest in a solo dungeon and then I moved on to the next area of questing. I spent about 30 minutes, selling gear, repairing, then started a few new quests and was about half way through them when suddenly my game crashed. When I logged back in, everything I had done since leaving that solo dungeon was reset, my quests, the items I found, everything. I have had issues like this in the past on other single player games, never once on anything that was MMO however. As for what I was doing when it crashed, I was looting a backpack and then it crashed.
