I am not sure if this right or maybe I have got to the end of the free to play.
I am 20/43 on Kithgard and Backwood Forest 42/70.
There used to be an arrow pointing which level to play next. Now there is only 1 on Forest pointing at paid mission “Boom! And Bust” and in Sarven desert there is the same situation arrow points at paid mission “The Dunes”. I unable to play any new missions.
Also in my opinion the dungeons link from Backwood Forest to the Dungeon does not work.
Loving the game!
