I have been playing a coop game with 2 friends, hosted on my xbox one X. We are probably at least 50 hours in, and just getting to end game content. Last night, while fighting a boss in the Wine Cellar, the game completely froze and my friends were dropped. Since then I have tried 8-9 times to restart the game, both in single player and coop, and every time it crashes to the xbox home screen.
I have tried restarting the xbox. Have tried joining an online server (worked fine), quitting, then trying to launch single / coop, crashes after a ~1min load screen.
Is there any fix for this? This has completely taken the wind out of our sails, we have been loving playing together, I even just bought the year 1 DLC pack and was considering buying the year 2 pack, but if our game save is lost we will be absolutely be quitting this game and would be extremely disappointed.
