I'd like two corrections made to my Halo 4 statistics. Can that be done, and if so, is this the place to ask?
First: On March 26, I let someone else use my Xbox without signing out first. They started Dawn on Normal, quit, then dropped to Easy and played a bit more from Rally Point Beta. Can those games be deleted from the recrod?
Second: The week of April 28, one of the weekly challenges was "Infinity and Beyond"; completing the level Infinity with the Mythic, Thunderbolt, Tough Luck and Tilt skulls active. I did so (on April 30), but discovered afterward that I'd been disconnected from Xbox Live due to a local connection problem. Is it still possible to get credit for the challenge?
