Yes, all three were in the northeast corner. Solipsist said that the missions only spawned in NE corner. I just went with that, and that proved to be true.
My priorities were to do everything in the NE corner, so that the mission could spawn if it wanted to, and then to do all treasure missions to bring the missions up in queue.
I can't tell you all how glad I am to be done with this shipyard crap (and the garrisons, for the most part). Has to be the most inane "game" ever contrived.
So do all northeast and do all treasure maps on the entire map to get treasure missions up in que faster? I had been only doing everything popping up on northeast corner.
