Quest Issue: Treant Fists

[Zarcath]

I'm trying to do the Treant Fists quest in Kerra Isle.

I found the banished kerran but he doesn't respond to the keyphase "puab sent me"

When I give him "puab's token" he gives his speech about the Ashen order and returning the remains of Thipt but he doesn't give me the box to combine the bones in. He also does not respond to questions about Thipt.

I've seen other monks wearing the Treant Fists so I'm not sure what the problem is. I have empty space for the container and I don't have the container in my bank or anything like that.

This is my 2nd time giving him the token and not receiving the box needed.
