I was play solo legendary to go for achievements. I got to the level called "The Package" finished the level. and it said achievement unlocked. So then it brought me back tot he game lobby then i when to to look at my achievement library and it tells me 0 gamerscore. So i signed out then back in. and it reset everything. Except my rank. But my emblem armor etc... gone. and it says i have no levels beat on legendary now
and i don't have the achievements.. has this happened to anyone else?
