Crystalline Memories has become my nemesis. Over 3 characters who have completed it, over 2 accounts, I have logged a total of 8 attempts. Each time I attempted and failed to finish, I randomly disconnected just after the time that the Crystal Guardian was defeated, usually as the Glint dialogue was playing. When I go back in, I have to re-do the boss fight. Just had my second d/c on character number 4, and I'm fed up. To say this is frustrating is a gross understatement. I have gone through a recommended client repair, no difference. Generally, I have managed to get through this mission by bringing guildies along so we power through it super fast. I can easily solo the mission, but need help to FINISH the mission? Not fun, Anet. I have tried this at various times of the day, and have had no internet problems with any other game or software - just GW2. I get the occasional d/c in PvE, in new and old maps, but missions are where it happens almost predictably. Please, would you at least acknowledge that there is a problem, even if you haven't been able to trace the cause yet. Just let us know that it's being looked into? I want to get back to enjoying doing story missions.
