It seems "Levels Top" quest did end prematurely, thus you couldn't obtain it's rewards (beg skill and the others). I'm not sure how you had it before this, since you mentioned it was lost in a recent save.
Anyway, quick fix is reaching level 16 then sleep (save) and reload the game (or full restart). The skill should be auto unlocked.
I have provided you with a fixed save (via email).
