My son and I were playing a game together, he is 8.  He has worked so hard to get all diamond tools and armor, then the netherite update came and we upgraded everything on a game together.  Well... after we were done he saved and quit.  Went to start the game tonight and all his inventory was gone.  So now he doesn't want to play anymore, he said why play a game that looses all your stuff after you work so hard.   So that's where I'm at.  Hopefully there is fix for this were we can get everything back, there was alot of effort put forth to get where he was and its an issue that needs resolved.
