ToME: the Tales of Maj'Eyal

In my current game, I can't find the sixth piece of lore (the "key" to Sher'tul) in the Old Forest. I understand that this is supposed to be in level 4 of Old Forest, but I've searched the level thoroughly and still can't find the final missing journal entry.

In this current game, there's a huge vault of thieves and trolls in level 4 of Old Forest. Could this be why the journal entry is missing? Is there any way to edit or add the journal entry back in?

If you can't find something that should be in a particular zone and there's a vault, it will likely be in there.

Also, the vaults in Old Forest are generally easier. Furthermore, sometimes you have to dig to rooms that aren't visible.

Weird, i thought i had written an answer to this.

Do you have access to vision or something similar?
I had one of the troll mire notes once in an area that could only be accessed with a digging tool or controlled phase door.
Was only a few tiles too, so it could easily be overlooked.

EDIT: Ok, found you posted this twice. Was that really necessary?
