Before the update a few hours ago, I had the task of fighting Belloq in Azteca on my Storm Wizard. My questing buddy received credit after the fight (we are on identical quests with these characters and do all quests together). I however, did not, and we had to redo the entire dungeon again.
Immediately after the update I went in the SAME dungeon on my Fire Wizard along with 3 other random people having same quest. They all received credit after we defeated Belloq, except for yours truly. Now, I have to go back and do it all over...yet again. I have 6 Archmage wizards to take through Azteca, and while I am loving the scenery, I am quickly becoming disenchanted at the thought of doing that dungeon twice every time (if not more at this rate). I have talked to some others and a few had the same problem.
One of the random folks I did the dungeon with first time on my fire managed to find me in his chat log and informed me that he in fact did not get credit for the quest and didnt realize until he had ported out after it was over. We are in there now DOING IT AGAIN.
We just finished, and I got credit for the dungeon. Alas, the guy that was with me on his 2nd attempt, did not. He has to do it yet AGAIN. This is simply ludicrous.
