Had this again playing Living World 2 storyline, Echoes of the Past. Was trying to finish the quest but had the Connection Lost error before starting very last boss. Now have to play all over again. All prior missions in LW2 were great, I did get a lost connection at the end of Dragons Reach 2 but it appears the game completed as I received the credit, could it be that the devs may have put some fixes in place?
