Hey ya’ll, just wanted to report one thing that happened to me on my first character through since release. I did play through beta before so I have a little bit of reference I believe to this.
I was playing on my rogue earlier today and when I reached this questline, involving Vigo and Neyrelle I did the first cutscene interaction and then the following stuff leading upto Vigo opening the mines for us. When I clicked to enter the dungeon, instead of bringing me to the entrance, I was spawned all the way at the point of the quest where Neyrelle branches off to open the door for us through the small gap in the wall. For some reason it skipped the entire first part of the dungeon. It was also a bit bugged upon the teleportation, I had to back track a bit and fight an elite before Neyrelle and Vigo finally did their scripted voice lines in that room. Was very odd. Not sure if I could replicate it or not.
Thanks
