Achievement issues

OP iZactimus

Has anyone else had issues with Halo 4 backwards compatible not unlocking achievements properly?

To start, all of my prior progress was there when I booted it up. No issues. BUT, when I try to complete some of the achievements I do not have, they do not unlock. For example, I completed a couple of the Spartan Ops achievements that I do not have, but nothing popped. Same with some multiplayer/matchmaking achievements. Then randomly, 9 achievements popped all at once. I checked, but it was only some of the achievements I should have unlocked.

TL;DR achievements are not unlocking properly, if they even unlock at all.
