Need help with glitched achievements!

A few achievements won't unlock for me and I have no idea why. For example, killing and looting ten birds, killing forty enemies with shotguns and seventy-five with rifles, pulling five enemies off cliffs with rope pull, etc.

I even managed to unlock the achievement for owning 75% of the relics but the one for 25% IS STILL LOCKED. Plus I have about the same number of documents but neither the 25% nor the 75% ever popped. HOW???

Does anyone out there who experienced this but fixed it know something that can help me. I can literally find NOTHING all across Google. Just more and more people talking about this same issue but they can't find help either.

Halo 4 glitched achievements

This is currently a big issue with Halo 4 that has not been addressed by 343 despite several playlist updates.

Several kill based achievements are glitched in Halo 4 multiplayer. Fortunately, only 1 achievement is glitched for me, but it is the final one I need, and I know there are several players dealing with similar issues with several achievements.

The achievement I have glitched is Ashes to Ashes. Is there any known way to get these glitched achievements?

343 industries please help me. I need help unlocking a glitched achievement in odst halo master chief collection. Audio logs. I've Done Everything And Was Told To Contact You

 

Update: I have completed the game 100%. Literally everything. I unlocked the story complete achievement, the achievement for finding ALL collectibles, but i still haven't earned a couple of 25% achievements and at least one 75% achievement. I also raided
ALL tombs and still haven't earned Intellectually Superior.

What... do... I... do???

 

I'm in the same boat , completed the game (and didn't get the achievement) all tombs done , 100% the weapons and rifle kills really starting to annoy me , didn't even unlock on a second play through

 

I'm in the same boat. Completed the game twice to 100% and still not unlocking 3 of the big achievements for 175g. The xbox one acheivement tile shows that I have 100% (when I compare to a friend), but still says locked.

 

I'm having the same issue with unofficial business achievement for completing the first challenge, I've done 5 now and still no achievement

 

I got home from work today and all the achievements have now unlocked

 

Same problem here I'm missing the achievments for ending the game and for collecting all collectibles....
