So i've been looking for over a half an hour for this girl named Brenda in Yaschas Massif 10AF to gain the quest of Misery's Bead but i can't find her anywhere. I'm using the official strategy guide and it says she is located south east of chocolina in the north.... I CAN'T FIND HER! I looked everywhere twice. Is it something to do with the fact that i already accepted 2 other missions here that she won't show up? I'm lost.
This question is a couple days old now, but if you haven't found out yet the answer is yes. I had the same problem but it seems that you cannot accept more than 2 side quests in the same area at the same time. You must complete the quests you have already accepted before you can accept a new one.
