I sincerely don't understand this goal, I just completed the 23 knights and then got a pop-up for another goal set called King's Honor, Farmer.

It is collecting the very same items and making the armors in the outpost, like why didn't this show while I was collecting at the beginning ? Initially I thought it was some grand finale prize but no just another repeat of the faire.

On another note I smash a Grand Jack O' Lantern and got a inflatable, still no pets for me. S8 must dislike my farm!
