I pretty much tried everything possible to get it working again, but nothing helped. So there I was unable to join the group and forced to leave the whole place without having achieved anything because of a bug. This was the first time I was really affected by bugs during my whole time playing AoC and I gotta admit I felt really frustrated and had to log out for a while to keep my cool. Now I think I understand the people who skip the whole place and wait for the mobs to get gray so they can do it solo. No matter how much fun grouping is, the place is horrible and should definitely be turned in to a group instance instead of the shared dungeon it is at the moment.
