Ok… I recently completed my 25th challenge and I didn’t get The Challenger achievement. I was wondering has anyone else encountered this problem or is it just me.
Nevermind… The achievement popped up but only after I completed my 28th challenge.

Yup. It takes some challenges to pop up 
Halo 4 has some glitched achievements (I didn’t get the achievement for completing the campaign cooperatively on heroic, for example). Don’t expect to get any help from 343, though. They are horrible with the community and act like they don’t know what they’re doing at all.

I still trust 343 but im starting to think this way also. some of the deicisions they’ve made have blown my mind.
bleep bloop

edit: seems so maybe run through each mission again
