Regardless the only way to get the quest book to work is to no longer be in hardcore mode, which means my choices are play hardcore without the quest book, or play with the quest book with infinite lives,
Yes it does actually, when i open the questbook it then says my lives are infinite and when you open to lan, it does change the game mode and there is only survival, creative or adventure, so there's no way to go back to hardcore mode.
So does that mean we can't play HQM Hardcore because of sync? That would make me super sad, if I open to lan and enable cheats it then gives me infinite lives, which I don't want :(
