Guild Wars 2

I have finished the story except for the last dungeon, wouldn’t I have gotten that?

I have “completed” Orr in getting all the vistas and points and stuff, but my achievement page says there is one place I haven’t uncovered and I have no idea where it is. Does it have to do with the dungeon? because I haven’t done it yet and I can’t think what else it would be.

If it helps, there is a picture of my map attached.

After the last update I wasn’t able to use transmutation stones anymore. They just don’t work. I am also aware that the basic ones don’t work on level 80 items. They just don’t seem to work period for me. Anyone else have this problem?
