Recently, a few days before Halo 4 came out, I encountered an odd glitch on Halo Reach. I was playing a matchmaking game, and after I finished, the game said I was promoted, even though I didn’t earn enough credits to rank up. I thought this was weird, so I restarted Halo Reach, and I was back to my old rank. So the glitch seems to have sorted itself out, but I wanted to post it here.
