I did the Return to Gianthold Chain (all 4 quests), but Draznok, the quest chain giver is unresponsive, so I can't get an end reward and others in my party couldn't either.

There is "Bring word to Draznok" in the Campaign System Objectives display and in the Quest Journal there is still "Return to Gianthold: Madstone Crater" open, although I finished the quest and have got an end reward from Hworrl.

I tried to abandon this one, but it says I can't abandon the quest while on this goal.

I retook Return to Madstone Crater and in the Quest Journal it says "Level 14 Quest"...

I will repeat it and see what's happening, but does anyone have the same problem or know a solution?
