I lost time how many times I finished the "Gravemind" stage in Halo 2. Six maybe. Or more. But, this stupid Halo Waypoint simply dont register it.
And most part of Halo 4 campaign too.

This online achievements unlocks are simply STUPID.

I remember when Bungie launch Halo 2. We are able to see were in the map we died, who killed us, how and the time. Now, ten years later, 343 is unable to make simple achievements to work. Thats down the drain this thing is going. Lets not mention the other problems with this title...
