Xbox One, Halo 5 and MCC, several single and multiplayer achievements not unlocking.
It’s been a few months that this has been happening. A friend and myself went through halo 5 and some of MCC achievement hunting, he ended up with many more achievements, and I haven’t unlocked one since June. As a test, I tried to complete MCC’s CE achievement Wraith Hunter, short sweet and simple. I even waited for the last tank to shoot at me to ensure it would register with the tracking, and it didn’t unlock or even teack. I tried 3 times. After talking to Microsoft and Xbox support, I was informed this is a known issue and that I should come here, but I can’t find a way to fix it here. Hoping someone can show me an easy fix.
