Career Milestones Erased??

I recently tried to access Halo Waypoint from my xbox 360 when playing Halo 4. When I clicked the option to go to waypoint, my xbox crashed. I thought this might be a one time issue, but sure enough, every time i went to Waypoint from Halo 4 it crashed my xbox. So i looked up the frequently asked questions, and sure enough, I saw what was wrong. 343’s advise “Fix it yourself! Delete Halo Waypoint and then re-download it” so of course I followed this advise and sure enough Waypoint works again.

However, when i re-logged into Waypoint, All of my career milestones were gone! This might not seem so bad, but it is a pretty annoying glitch if you actually care about that sort of thing. I think when i deleted Waypoint, it deleted my milestones along with it. So even though I have every achievement in nearly every Halo game except 4, my milestone is set at 0 and it refuses to recognize that i have completed any of the achievements. Is there a way to fix this or am I just SOL until 343 releases a patch?

That happened to me as well. Last night after completing the whole campaign on Heroic, my whole campaign progress was deleted, and I never got an achievement for completing Reclaimer. It also says I haven’t found any of the campaign terminals even though I have the achievement to prove it, and when I need the terminals to try unlock something…it get’s pretty annoying.
