Hardcore Character Dead due to Game Crashing Issue

I answered your other thread. Given the troubleshooting you already completed the recommendation would be to consult with Xbox support if the console is shutting off still and continue with the repair option they offered.

Note: Yesterday we did experience a DDoS attack on our services this wouldn’t have turned off your Xbox or crashed the game but it would have caused a lot of connection issues.

As for your ticket it sounds like you put it under PC crash instead of console crash but we wouldn’t be able to assist much more in this case as we believe given the behavior and troubleshooting this is more likely a console hardware or power issue.

Thank you.
