Has anyone else noticed server issues with Reach about once a week? I signed on yesterday to play and do the challenges, and at the end of the game it was registering me as "offline" and said "credit limit reached". It was the first game of the day, and suddenly I couldn't do any challenges (it didn't register the two I finished in that game), couldn't play reach at all. I've noticed it happens once or twice a week, always kind of late at night when it shouldn't be crowded. Anyone have any guesses as to what could cause this??? It was so annoying I ended up playing H3 BTB for a couple hours and going to bed.
