I am having a issue were in the Halo CE I have completed the Legendary, Easy and Normal but for some reason in the achievements it says 9/10 completed on all of them. On the choose mission I have Legendary icon on all of them. Please tell me what to do to get this fix. I have done everything Microsoft has told me, uninstall and reinstall both game and profile. I even have played all mission again. I have played and completed 356 campaign mission. I have also made sure to play though each mission without saving and exit, just completed the mission in one go. On my waypoint profile it says The Truth and Reconciliation is not completed, but in the choose mission it has the normal icon in solo and co-op has the Legendary icon.
Hm, did you beat all the missions on co-op Legendary or did you beat one solo?
I myself am having issues. My game shows more legendary completions than on here. While for some reason my game decided to skip giving me the achievement for 343 guilty spark . -.-
