Halo 3 ODST: help getting a achievement?

Im playing it on the MCC and I did the uplift reserve mission before finding the clue. Now when I go to get the clue it’s not there and I can’t get the achievement. Does anybody know how I can get the achievement for finding the second clue?

If you’re looking for people to play with you, check out the Recruitment section of the forums.
