Achievement "Wall of Recognition" Glitched at 86%

I’ve completed all missions with gold medals on easy. Service record shows gold medal on all missions on easy (not to mention some on heroic). Hard reset console and reloaded game (i am connected to Xbox Live), have waited 20 hours, completed the first 3 missions again getting gold medals on easy, completed another mission on normal–still no achievement. Wtf…

Others have reported having the same issue, with numbers ranging from 86% to 93% on achievement tracker. Fix your sh**. Achievements aren’t hard to make work. I promise. Developers do it correctly all the time. The original Halo Wars didn’t have these achievement issues on the 360. I know because I got every single one of them. Do your job.

I don’t have issues with this achievement. I got an achievement is unlocked in the Halo Wars DE.

You need some a few easy, normal and heroic in each mission plus; legendary is possible. I did played in the easy, heroic and legendary in the missions with all “Gold Medals” to unlocked the achievement this.

yeah same thing here
343 what are you doing?

same for me, i have all gold medal but the famé says i m at 93%

Same issu here. How are achievement glitches still a thing 343??.. tsk tsk

So this hasn’t been sorted yet has it. It’s been months and mine is still stuck at 80%. So annoying as the only option seems to be redoing every mission in every difficulty in order to trick the game.

Why 343? Why?

Would it not have been too hard to tie the achievements to your service record as that seems to be correct all the time and just supports how wrong the achievement tracker is.
