Thackeray scavenger hunt issue

Not sure if this is a bug or not. I've got 2 accounts, and 3 of 5 characters have completed WiK questline (2 that haven't are on same account).

I wanted to get the sacks of random junk, just for the heck of it. I can take one of these 2 characters that haven't completed WiK outside EotN, and Thackeray shows up. If I party with the character on the alternate account that has completed WiK, Thackeray doesn't show up. I make the party leader the guy that hasn't yet completed WiK.

I noticed I had some of the daily WiK quests on the alternate account, so I removed them and tried again - still no Thackeray. The wiki suggests he should be there: "If the party leader has access to the scavenger hunt so do all the other party members, so you can still complete it with help. 82.143.219.87 02:31, 10 January 2011 (UTC) "

Hmm, I know they're crappy, but I just wanted to collect a stack of junk hehe. Any suggestions?

If the party leader has access to the scavenger hunt and so do all the other party members

Afaik party leader does not matter, one person that has a quest enabler/disabler takes precedent.
