The day crimson came out i bought is yes purchased it for 800 mp not the free trial glitch thing. On that day i got all the achievements that just came out for the game with the crimson map pack. Just now i got the achievement clay pigeon and realized that i have to unlock the others as well.
Seriously 343 this is starting to get old.
Did you boost them all on day one?
I’ve had achievements disappear on me too. Most of the time it was due to receiving it in error. Although sometimes it was bad server communication, which is a big irritant because some of these are very hard to get.

No I focused on one achievement at a time and did them legitimately.
