I had the post game carnage crash issue where if you press Y and look at the postgame carnage, the game would freeze and crash to dashboard. What i did to solve it was:
- Go to dashboard, press the menu button and quit out of halo.- Press the menu button on Halo MCC and select “Manage Game”- Select the save data on the right hand side and and delete from console NOT DELETE EVERYWHERE! If you select delete everywhere, say bye to your campaign progress.- Once that is done, go to the xbox settings and click on Power and Startup. Ensure that it is NOT set for instant-on, and set it for energy savings.- Use the menu and turn off your xbox. Once your xbox is off, pull the power from the power brick for around 10 seconds.- Plug the power back in and start your xbox and halo mcc. It should pull your saved data from xbox live.
Let me know if it works.
