I am trying to get all 700 achievements (currently at 192/700) for the master chief collection and so far I’ve had absolutely no problems besides some achievements not unlocking immediately. But there are 3 achievements on Reach that will not unlock for me. I have tried many times to unlock them but they never do. The 3 achievements are They’ve Always Been Faster, Play Us A Sad Song Claude, Jorge Can’t Have All the Big Guns. If anyone knows how to fix this problem, I would appreciate the help greatly.

Sometimes the archivment message doesn’t see on the screen but if you go on the Xbox Companion App are unlocked try to chek and tell me 
Ciao!
I’ve had a similar problem before where they wouldn’t show achievement unlock, exiting out of the game then going back in worked for me.
