Quest Issue: some npc's don't respond

[Halladar]

Hey I put in a thread about the Millers in QH.

I've checked several times and they do not respond to me.

Baobob answers when hailed and has [sister] and [garmet] as keywords. He gives me no text with either.

Chanda responds when hailed, and also when you tell her "baobob sent me."

No text when you respond to [clothes] though.

I've had this problem with other npc's as well. Some in halas.

I have the titanium client and I think I've installed the files properly.
