It's happened to me in the past on blops2 can't say on ghosts not really paying attention to patch challenges. It's frustrating but not the end of the world
Probably something else IW will need to patch. I completed an objective and it said I got some spiffy new uniform. With the current character I had, it wouldn't show up and was still locked. When I went to change another characters uniform, it showed up there right away. I restarted my PS3 and it was the same even after that. Yet more poor coding on IW's part. I still have crappy uniforms
Yes I believe it has I found the patch unlocked now and the uniform, thanks guys.
