Cant accept Guildhest?

Im on the Main Scenario quest 'Hest of the Best', but I cant do the Guildhest..? I dont see it on my Duty Finder list at all. I closed the game and relaunched it, and theres still no option for it. Ive tried talking to the Battlewarden and still no success. :mad:

They unlock in succession... you need to do each one in order. Completing 'Pulling Poison Posies' will unlock the next one and so on.

Edit:

The one you need is there: "Hero on the Halfshell" (Level 15) -- read your quest text.
