Glitched HALO 4 Achievements

What your experiencing is a bug in Halo 4. Alot of people are having problems with that achievment and many other ones. Some people cant unlock them at all. IF i were you, just be happy your one of the lucky ones and are actually able to unlock the achievment.

 

Halo 4 achievements glitched

When i look at your account/achievments, It says that you havent unlocked those achievments. As of right now, your total achievment points for halo 4 is 260. I added all your halo 4 achievments up and it does in fact come to 260. My advice, delete the Crimson
Map Pack, clear your cache, then redownload the Crimson Map Pack. Also, you must be playing in the "Crimson Map Pack DLC" playlist on matchmaking. The achievments wont unlock in Infinity slayer, capture the flag, etc..etc..

 

I just started playing my brand new Xbox One and all my achievements are at the 100% and unlocked, but the 335 pops up, when it should be 415, why does this happen ?

 

Well, mine finally got to the correct 450 points for my achievements.

 

I'm having the same problem with 3 of the intel achievements. I wonder if they care enough to fix them. It really annoys me because I put some significant time into retrieving all the intel in this game and I only did it for the achievements. Please fix
this problem. I'd be more than happy to submit any screenshots needed proving that I have %100 of the intel items.
