I am on the mainland, but it is frustrating that i cant do the historical mission of Jokanur Diggings, while other people from cantha/tyria are...

Did al that i explored every side of the map and city i cannot find any others quests.

I have the same problem here, i cant enter this mission, or i dont know how to activate him. I did battle preperations and i am already a general....
