Reach achievements blocked on Waypoint?

I don´t know what to do, I have plenty of achievements unlocked in Reach, and they used to appear as unlocked in Waypoint. Now all of them appear as if like I had never unlocked them.

It´s pretty absurd when you go to my profile and It says that I beat the campaign on legendary solo, but then “A Monument to All your Sins” appears as locked.

What can I do? Even my milestone went down, it was around 53 and now it’s 42.

edit 1: I deleted waypoint and downloaded it again, now my reach achievements show up, but my halo 3 and odst achievements dont. Great. My milestone went down to 32…

i got the same issue man… my halo wars achievements aren’t showing up. says that i haven’t even played the game. but i have 40 achievements for halo wars. plus my milestone score went from 64 last night to 43 today.

Mine is a little strange too, I have Rank 75 but when you look at Halo Wars it says I haven’t played it yet? Also says I have 296/303 Acievements but I am only missing 1. Running the Show

Yeah, same thing for me i just sent from rank 37 to 13.
Halo 3. Reach and odst are completely screwed. It’s like my profiles are corrupted. I just deleted waypoint and am reinstalling it now.

If I have to redo the last mission of reach in legendary solo, I’m gonna kill myself instead, way less painful
