So I have completed halo 4 on CO-OP legendary but I’ve not unlocked the achievement due to my halo stats resetting for a brief moment a few months back. Now in order for my xbox to register that I have finished the campaign on legendary all over again!
Is there anyway to undo this?
All of my data to prove I have done it is on Halo 4 Stats.
This was clearly not my fault, so how do I go about resolving this issue?!
