Halo Wars 2 Achievement is Glitched Please Help

Hello 343i,
I made a post about this before and it was not replied to, so I contacted Microsoft support for help and they were unable to help. They in fact told me to contact you guys via this website. The issue I’m having is with the “A Lot Extra” Achievement not unlocking. It is stuck at 94% and after following the solutions on the Microsoft website, and after multiple completions, updates, it won’t unlock. I have almost all Halo Achievements, so PLEASE PLEASE PLEASE help me I don’t know what else to do.

I’m having the same issue, I’m stuck at 94% completion for A Lot Extra achievement, done the bonus objectives multiple times and it shows that I have completed them all in the menus. Any help from anyone would be appreciated.

I’m stuck at 94 as well. Still nothing?
