I think they fixed this already, try saving and quiting and then reloading your save again.
"Restored some lost progress to players who have had their profiles reset. To ensure you are credited for as much progress as possible, please load your character, select "Continue" on the Main Menu, and then "Save and Quit" after you enter the world. Repeat this process for each character in your character list." --- GT: KingRaven42
Not fixed yet on Xbox. Its supposed to be in the next patch though. It is fixed on PC. --- "If your going to ask someone to save the world, make sure they like it the way it is" http://www.youtube.com/user/Drakeskull23
