I've just done an entire run of the first part of Castle Darkmoor and I'm very upset because I had access to the dungeon and did the entire thing, yet when I got to the upper halls I couldn't enter the second part, and didn't get credit for the first part! It said I still have to "Explore Castle Darkmoor" even though I completed the first part.
I'm upset because it's an hour of my time wasted, and it's just annoying that the quest didn't register. Is there any way I can get the credit without re-doing the whole thing?
