I've done Fort ranik mission twice, and i've done northern wall mission twice, because i keep joining missions i didnt think i've done.. Where is the next mission?

The next mission you need to be on is the one that goes to Rin. Once you leave Rin (on another mission) you'll end up in Yak's Bend. I can't remember what the mission to Rin is called, sorry.

Just follow the primary quests that you get. Primary quests lead to the next missions.
