Campaign end of mission report fail

I just beat the mission guardians, and i was honestly excited to see the stats. Instead what i got was a buffering circle and an error message. I am probably more upset about this than I should be, but 343 please try to fix, or cut back on this in future games. Or do nothing, either way i just wanted you to know that it happened. I figured maybe the knowledge of a bug or server issue might be helpfull in some way.
