When I attempt to unlock the Raider 'dsst' shoulders through Waypoint it seems to erase my completion of the chapter "Hunting Trip"
I have been able to replicate the bug twice so far.
1. Start ''Hunting Trip'' on legendary. (Solo)
2. Complete ''Hunting Trip'' on Legendary
3. Wait for exp screen to finish displaying score.
4. Check to make sure that it did in fact count completion
5. Exit Halo 4 and to Waypoint through the interface in Halo 4
6. Check Spartan Ops in Halo 4 to make sure it counts credit. (It did 2x for me)
7. Press X to access Classifieds and enter appropriate code.
At this point I should have my shiny new shoulders but instead I receive the message, "All pre-requisites have not been met" and when I go back to check Spartan Ops it states that I have not completed Hunting Trip not only in Waypoint for Halo 4 as well.
