I dont think you understood the question.
Sardaukar wanted to know why they are not getting the quest for his other accounts, they understand that the npc will be there extra days (for those who are still working on the quests/getting tokens), just not why they cant get the quest for the hat token.
as for that answer, I do not have one (I would check, but I did all the quests on my alts the first day

)----the only possibility I come up with is that you had not logged into those accounts since the last dragon festival? (it might think you had done them then).
