Disappearing quests on log-in?

[Synacy]

As the title states,

When I log off the game and log in a few hours later, whatever quests I had on my account seem to disappear. This unfortunately happened with all my characters. I had completed all the BL quests on my witch elf last night for the armor pieces, but not the tokens. I had gathered all of the BL quests for the tokens before I logged off last night, and when I logged in this morning, I had seen that they all disappeared from my character. I had to run to each location to pick up the quests, again. Does anybody else have this issue of quests disappearing?

Its happened to me in the past too. The quests reappeared weeks later, even though i had retaken a couple of them. Not sure how to fix the bug though.

i reported this more than one year ago (and it is still dubious in bugtracker....) it is the BL quest which is making quest log bug and total reset, IT was 90% pre BL rework the DW quest, now idk what specifically make it bug . I had that bug on 3-4 diff toons and it happened randomly always when i have dw BL quest

MY advice is always give immidietly with out log out all completed Bl quest you have.
