I'm so disappointed, today I finshed halo 1 on legendery to discover that no mission completion achievments had been unlocking after mission 3, when i look in select mission all have been done on legendery solo but achievement progress is all at zero?? In turn the complete all missions on different hardness didnt pop ethier, I know some take a while to pop but they say 100% unlocking.... Also finished halo 3 co op legendery got the achievements but the in game progress says I havent??? Its gone from one problem to the oppisite, All i want to know is this fixable? Will it all correct itself? Will be a huge shame if i have to redo all i have already done. Huge Halo Fan XxKIWIxCHAOSxX Also anybody else havinging these issues? How do I get 343 to see this? Just would be nice to know they seen my post.
