Hello Folks.
Some additional, did not know if clear yet.
I have finished "time to Whaag" (T4 Greenskin), until the choice of the blue sword.
Strange getting one of the 3 rewards, without finishing the whole quest-line ?!?
Funny thing is, parts of the questline where still to do!
I went for the objectives and after a dc, everything was lost again.
All Quest-Logs and the correct NPC missing.
"the Ebon Flame" (T4 darkelves) I have found again yesterday, in Ch.18 and doin some quests.
After login this morning, all Quest-Logs where lost again.
I remember the task. It was: killing some Silverspear called Be... near the PQ "...Pool" in Eatiane.
"Anihilation" still missing at all.
Can find the NPC Rundalf (named something like that

) near his normal position and inside of the Anihilation cave, where you have to finish through interact with the altar...
So I thouht, that the quests all were still running, but invisible in my ToK.
I am afraid not to finish them, because of not exactly knowing which part now to finish.
Hope someone got the same issues.
It seems just occur at the Epic-Quest-Lines.
I would be very thnakful for some support.
