A little issue..

Sorry in advance if I’m breaking any rules. I haven’t spent any time on here or posted to these forums before.

anyways, I am having an issue with one of the challenges for Spartan ops… I’ve completed all 5 chapters on legendary, solo I might add… and I wasn’t awarded the xP from the weekly challenge and is still incomplete. I don’t really feel like going back and playing any them through them again. I know it’s a small issue, but I just have a thing for the weekly/daily challenges.

So, has anything similar been posted or mentioned on here, and was there any way to fix it? or would any of you have any suggestions?..
