This might seem weird. But basically I fell in the lava in the nether and I instantly went into creative mode. Now I feel bad because I cheated. My question is whether there’s a way to ‘go back in time’. I was thinking about going into the file of the world and maybe deleting the latest saves. Do you have any idea? Thanks.
Do you feel bad because you used Creative mode to survive in the lava? If so, just kill yourself using /kill (or by hopping in another pool of lava) and you'll lose the same items and XP that you would've lost if you didn't use Creative mode the first time.
