Knowledge Is PowerG 10

Complete all of the tutorial achievements.

There is an occasional glitch that means this achievement won't stay unlocked on your gamercard. It will appear to unlock everytime you finish a level, but after 10 seconds or so it disappears again, weird I know. To fix try the following:

1) Delete your save from the my documents folder. (Back it up somewhere if you want to keep your progress.) It should be called something like "584109eb_SojerManLan.sav", but will have your gamertag in it instead.

2) Open up tinker and do all 20 tutorial levels again (don't need to try and get all the stars)
