Regardiing the linkdead, I experienced one after about an hour of playing, from what I can tell I lost all movement data... I had tried and failed to complete a quest, far as I can tell the quest data was saved.. what wasn\'t saved was probably the positional data.
Auto-save or limited saves would seem very useful... least until the server has a more permanent way of storing semi-updated info(I lost 1 hour of movement).
