Upon startup of the game I am taken through the intro sequence (setting the language, brightness, etc.) and then subjected to the opening cutscene as if I am launching the game for the first time. I am then brought to my last save from before the update. Every time I exit my game after the Flames of the Nether DLC update it deletes any progress made during the session, reverting back to my last save before the update upon starting the game again. I have tried buying items from the shops as well as playing through full levels, and none of the items I acquired from the shops or levels, nor the emeralds I earned, remained in my inventory when I closed the game and started it again afterwards. I cannot even begin to express my disappointment and frustration about this game-breaking bug. I am hopeful that this can be resolved as expediently as possible so that I may enjoy the content I purchased.
