For the past 2 weeks I’ve spent my time beating all 4 games on Legendary (solo). However I discovered some achievements were not unlocking for example the achievement “Legend” has not been unlocked a long with some other single game Legendary achievements.
Also I checked on my service record and it says I have no completed the Halo 4 mission “Forerunner” at all. I love getting achievements and I am annoyed that some of mine are not unlocking so I’d like to know if there is a fix I could possibly do before 343 sort out the horrendous list of bugs.
My buddies and I are having the same issue. We completed MCC Reach Legendary in under 3 hours, beat par times on every level (and unlocked the corresponding achievement, Fast Fall) but yet don’t have the achievement “Generous Tipper” to complete par time on Tip of the Spear.
