Why am I having so many problems with bugged quest?

[ZackAttackXXX 0]

Completed the blood amber quest and got the plant salve, it wont let me cure the corrupted night dragon or even click on it. Secondly I cannot receive or complete any of the Libram quests. I have all the gold/materials I need and I'm over the required lvl. Is anybody else having these issues? What in the world is going on???

The libram one I have recently been made aware if from another user. It was fixed via GM ticket in game. Just make sure all materials are in your bags for it and a GM can complete the quest and leave the libram in your bags.

 

The other issue is a new one I have not seen before. Have you tried clearing your WDB folder?
