In stuck with quests.

[Eletiy]

I've some quests and I got somehow in stuck.

-Easamau lost his badge
-Sierann is waiting
-Talad's eyes and ears
-Govell Mihdren needs tatto ink
-From Archmaster to Archmaster
-The missing Equipment

Problem one with the Archmaster quest: I gave Govell Mihdren that exploding packet and tried some answers after this I crashed and asked a friend for the correct answer. After relog it didn't work but I'm 100% sure that I know the correct answers ...
Problem two with the tatto ink: I went to leverus and tried to get that tatto ink, but again it seems not to work and I'm again sure that I know the correct question for the tatto ink...

I know PS had (or has still) problems with handling more than a quest a once but since I can't discard any of them I don't know what to do ..

We've warned people about quests that involve the same NPC. Yes, conflicts still do exist.

In the event you're 100% sure you've got the correct answer, go back one step BEFORE the answer that you're 100% sure is correct, and try re-wording that.
