Glitched In Dungeons And Doguns When It First Came Out, Now Can't Complete Quest.

So when Dungeons and Doguns questline came out, naturally, I did it with a friend. I accidentally left the king's room before I finished the quest, however, and there is no way to get back there. This bug has been fixed, but I'm still stranded outside the king's room with no way to complete the quest. What do I do? Should I file a bug report for a bug that has already been resolved? Or do I just do nothing and leave the quest un-finished?

 

You can get back to the king’s room, there’s an entrance along the left balcony of the city into the slums. From there, blow up the iron gate again and go through the sewer and up the water.

 

I should have clarified, I meant in DND 4, in the very end.

Oh. What was the location where they were?

Edit: Try walking through the Molten Heights portal again.

 

I am having the same issue

 

The portal? Which portal are you referring to?

 

The one where Garaheth is summoned I think. According to the other guy it didn’t work though.
