I’ve Completed the entire Halo 4 Campaign alone on Normal, and now Co-op on Heroic. My friend earned each individual campaign achievement as we were playing, because he hadn’t played it at all yet. We both also earned the achievement, Chief Smash! I was surprised to see that after we completed the final mission, neither him or I earned the achievements for completing the campaign on Heroic co-op, or the overall Heroic achievement.
Thinking maybe I had somehow missed a level, I went to the menu to check my campaign progress. The menu said that I had only completed HALF of the campaign on Heroic, which is not true.
On Tuesday, I decided to do-over a couple levels that didn’t register. I did Forerunner on Heroic. After completing the level, I quit to the menu, and it STILL says I’ve only completed it on Normal! I later checked my achievements, and was shocked to see that my “Chief Smash!” had reset itself!
I’m not sure what’s going on here, but there is obviously something very wrong. I hope someone can help me with this and get things straightened out.
PS: At no time was there a power or internet disruption, nor was the Xbox tipped, bumped, jarred, or affected in any way.
UPDATE: I also realized that on Tuesday I had just hit 9mil cR on Reach, but the next day, I’m back down to about 8.98mil. ???
UPDATE 2: My “Chief Smash!” has been re-awarded, and I’m back to +9mil on Reach. But the Halo 4 Heroic Campaign completion is still incorrect.
