Try repeating a bunch of a easy lesson? It's actually not for doing them all but just 32 in general unless they changed it. --- PSN/XBL/Steam: mcnichoj Proud Vita/3DS/Wii U owner. Day one PS4/X1. | Wanting people to have full knowledge of the facts about a console makes you a fanboy.
Interesting point. Now that he mentions it... I got my Dojo 32 Lesson Achieve without doing all 32 lessons. I did the first 31, then repeated one and got the 32 Achieve. This was awhile ago, so not sure if it's relevant anymore after patches and whatnot.
