I was questing through there on a new wiz the other day and I ran into this issue a lot.
Inside dungeons, you receive separate quests right? These quests change as you progress through the dungeon itself.
The issue is that a lot of times there is a quest where you have to head to the area of the boss before you recieve a quest that actually tells you to fight the boss. In a few of the dungeons in Celestia, the area that you have to head in is really awkward as instead of the "head to" quest completing upon reaching that area, you have to move around and find a "sweet spot" for that quest to actually complete and shift to the "Fight the boss" quest.
This is problematic because if you miss the sweet spot and rush into a fight with the boss, defeat it, then you've broken the sequence and you can't finish the dungeon.
