I am having a same issue with the no easy way out achievement i did it a lone on normal a few times without dieing and on hard without dieing and with a friend without dieing and it never poped every one told me to clear my cache on the x box and restart it that never worked for me.... But maybe it can work for you trying clearing your cache on your x box and do another challenge if not then 343 will take a while to reply

I have the same issue. I called xbox support and they said to clear the cache and re-download your profile. I tried both and nothing worked. I have completed 27 challenges so far...One of my friends unlocked the achievement right on 25 challenges completed. Not sure what the problem is..343 please fix this problem

I also have done like 27 and no achievement. My friends all got theirs at 25. What gives?
