Last time I hailed her, I was level 9 (now 10). I've never received a 10 slot box from her. I've been able to get the orc headband quest from the frost guard captain, and some other quests from Halas, so don't think my character is bugged.
Yeah, she is bugged in several ways. I have a tunic material ready to turn in but she just gives it back. If it wasn't the correct item it would not have been able to combine in the box so I know it was correct. I have petitioned and turned it in on the bug list. Wiz even toyed with her for a bit one day till I had to log out.
Patience with her is all we can do. The quest rewards are better then studded armor with stats. Very much worth the time and effort to do them. Pantherskin is the replacement for this armor on my BST.
