That's a shame. I think I've passed that point already. If I go back to whatever place that was, will the messenger show up or do I have to clua him in?
The mod difficulty is currently being worked out, and toned down. Difficulty cannot be sorted out till the AI and areas are sorted, and this has not yet been completed.
I would reccomend that you start from the beginning of ToB.
I heard earlier that you couldn't get the message to start the quest until you came by the place where the Tethir soldiers attacked you. Has this changed?
