Last night I was playing Matchmaking. During a Halo 3 game on High Ground I encountered a number of issues. At one point I boosted into a walking player in a Ghost, bounced off them and went flying away, at another point I respawned and my weapons were completely invisible. I couldn’t see it at all, couldn’t see my melee, reticle or gunfire. Much more seriously, when I used a Grav Lift my game froze for 30 seconds and my console shutdown. I have had no other issues with my console, nor with Halo MCC.
