One of the main quest is not working for me. is there a way to abandon it? im stuck there for very long now. do i need to restart my character…
Press F5, click on the quest and finally click on ‘Abandon’. 
doesnt work on story quest unfortunately.
This happened to me.
My quest for the church door was bugged and I couldnt progress with the story.
Dont know if this actually did anything, but i shouted my problem.
Restarted my client about 10 times.
Then 10 mins went by as I was about to log off and randomly I was able to do that quest again.
Honestly no clue what happened.
Ah… Maybe it is caused because the server is strained so much due to the players. Hmm…
