Prolly coz there are a couple quests at the Shadowthread Cave that are essentially part of Shadowglenn, but not listed there?

Wholly interface switches when you enter the cave, but it doesn't select a new zone. Shadowthread Cave zone must not exist in Grail as a zone then? Maybe this is the problem

The missing quests are:

Webwood Corruption [28726] and Vile Touch [28727]

I looked in the exisitng zone, but it didn't show up, and a search revealed nothing. Also the All Quests search failed. so I'm guessing these funtions are currently not working for 9.0.1

Got another LUA report after it tried to search All Quests:

Then "Wholly requires Grail version 112 or later in chat
Wholly is absent from Menu/Interface/Addons tab

However, no errors going into cave.

The message from Wholly indicates that Grail is not actually loaded. Basically once Grail fails then both are not going to be there. It is weird that you are getting a message with SelectGossipOption in it because the code checks to see whether it exists before attempting to hook it. Can you do "/dump SelectGossipOption" and see if it prints out anything because something else could be defining it.

I just updated Grail on GitHub. Can you use that to see if this problem is fixed?

Had nothing but Wholly and Grail running

/dump SelectGossipOption
SelectGossipOption=nil
empty result

I cannot explain it. I do not have this problem in either Shadowlands beta or Retail. The code in Grail only attempts the hook the function if it actually is not nil. Admittedly it does not check whether it is a function versus any other type of object, so that is not the best it could be, but if it is nil it should not even attempt to hook it.

Re-dowloaded, got a newer version.
All OK now, including the cave. It's a different zone.

Cool.

I just pushed a new Grail that sets her to be near in zone 58 which is the cave. Now things should appear in Wholly.

Sorry for the late reply, I've been busy. I went back to it on a new char, and it's no longer throwing up the lua errors, however Wholly still switches to a blank zone, with no quests showing. They don't exist in the Shadowglenn zone either, but they are in Teldrassil.

I mean, it's working fine, but if you want to check the book while on these quests, you will just get the blank page:
